In `@emergency-support.html`:
- Around line 226-238: The addHelper function currently uses innerHTML with
unsanitized helper.name and helper.dist and embeds helper.name into an inline
onclick string, enabling XSS; change addHelper to build DOM nodes with
createElement and textContent (e.g., create div.helper-info, strong, span, and
button elements), set the text via textContent for helper.name and helper.dist,
and attach the click behavior to the button using addEventListener (or pass the
helper identifier via a data- attribute) instead of an inline onclick that
interpolates raw values; update references to helper-item, connect-btn, and
connectToHelper accordingly so no user-controlled string is injected into HTML
or event handler attributes.

In `@INSTALLATION.md`:
- Around line 329-339: The documentation incorrectly claims passwords are hashed
with bcrypt; update the INSTALLATION.md security section to remove or negate the
"Currently uses bcrypt (already implemented)" statement and instead state
clearly that password hashing is NOT implemented and must be added before
production (e.g., implement bcrypt/argon2 in the signup handler that currently
has the comment "In a real app, hash password here!" in server/index.js), while
keeping the SQL parameterized queries claim intact.

In `@sample.html`:
- Around line 595-1188: The file contains a full duplicate of the HTML document
(second <!DOCTYPE>/<html>/<body> block) which creates duplicate IDs like
calc-display, page-calculator, s-name, etc.; remove the entire duplicated second
copy so only one HTML document remains, ensuring unique elements like Navigate,
Auth, calc-display, page-signup, page-code, page-dashboard, and
s-name/s-email/s-pass exist exactly once and keep the first (original) instance;
after removal, verify navigation and DOM queries (getElementById calls) still
resolve and the app initializes as before.
- Around line 527-538: The calculate() function uses new Function('return ' +
calcInput...) which is equivalent to eval and allows arbitrary code execution;
replace this with a safe math-expression evaluator (e.g., integrate math.js or a
lightweight parser) and evaluate only numeric expressions after
sanitizing/replacing display symbols (e.g., convert '×' to '*') and validating
the token stream to allow only numbers, parentheses and math operators; update
the try/catch around the evaluation to call the safe parser (instead of new
Function) and set calcInput = 'Error' on parse/eval failures so the rest of
calculate(), updateDisplay(), and the Auth.login/login-check flow remain
unchanged.

In `@server/index.js`:
- Around line 49-62: The /api/auth/login route currently returns the full DB row
(db.get callback) which includes the plaintext password and also implies
passwords are stored in plaintext; stop sending the password by omitting or
deleting the password field from the response object and change authentication
to use bcrypt: fetch the user by username only (db.get with username), then use
bcrypt.compare(providedPassword, user.password) to verify; ensure user
creation/registration code (e.g., createUser/register handler) stores
bcrypt.hash(password, saltRounds) instead of raw passwords so login compares
against a hashed password.
- Around line 479-497: The nested db.run for updateSql is using this.lastID from
the inner callback (which is for the UPDATE) instead of the insertSql's
insertion result; capture the inserted row id inside the outer insertSql
callback (e.g., assign const insertedId = this.lastID or let insertedId =
this.lastID) and then reference insertedId when sending the response in the
updateSql callback and log; update the references to this.lastID in the
updateSql callback to use that captured insertedId so the returned id is the
comment's ID from the INSERT.

In `@src/App.jsx`:
- Around line 11-25: The code uses eval(display) in Calculator.jsx (replace
that) which is a code-injection risk and the universal unlock string '1234=' is
hardcoded in App.jsx handleUnlock and in Calculator.jsx; fix by swapping eval
for a safe math expression evaluator (e.g., integrate mathjs or implement a
simple tokenizer/evaluator and use that in the Calculator component where
eval(display) is called), update Calculator methods that rely on eval to call
the safe parser, and make the unlock code configurable instead of hardcoded by
exposing it via a prop/state or config (or per-user secret stored on the user
object) and add a clear comment in handleUnlock and Calculator explaining the
intentional disguised-calculator behavior and security considerations so future
maintainers know why a default exists and how to customize it.

In `@src/components/Calculator.jsx`:
- Around line 30-33: The component currently calls eval(display) inside the
Calculator component (where setDisplay is used) which allows arbitrary code
execution; replace this with a safe math parser such as mathjs: install mathjs,
create a restricted mathjs instance (disable/import and other dangerous
functions like createUnit per mathjs security guide), then call that instance's
evaluate/parse on the display string and setDisplay to the resulting value; wrap
evaluation in try/catch to handle parse errors and avoid executing any raw eval
or Function constructors anywhere in the codebase.

In `@src/components/SOS.jsx`:
- Around line 26-58: The manual setTimeout (timeoutId) races with
navigator.geolocation.getCurrentPosition's timeout and can call
sendSOSWithoutLocation twice; remove the manual setTimeout and its clearTimeout
calls and rely on the Geolocation API's { timeout: 5000 } option so only the
geolocation error callback calls sendSOSWithoutLocation, keeping the existing
success and error handlers (references: timeoutId, sendSOSWithoutLocation,
navigator.geolocation.getCurrentPosition, the success callback that posts to
/api/sos, and the error callback).

160-167: ⚠️ Potential issue | 🟠 Major

Avoid publishing default credentials in documentation.

Hardcoded test credentials (testuser / password123 and unlock code 1234=) in a public repo are a security risk if these defaults ship to production. At minimum, note these are for local development only, or better yet, seed them via a setup script rather than documenting them publicly.

debug.html-1-55 (1)

1-55: ⚠️ Potential issue | 🟠 Major

Ensure this debug page is excluded from production deployments.

This page lets anyone clear all localStorage data with a single click. If it's accessible in production, it's a support/UX hazard. Consider either:

  • Excluding it from the production build (e.g., via Vite's build config or a separate directory).
  • Gating access behind a developer flag or authentication check.
.gitignore-1-24 (1)

Add .env* patterns to prevent accidental secret commits.

The project depends on dotenv and documentation references environment variables (e.g., VITE_API_URL). Without ignoring .env files, secrets and credentials risk being committed.

INSTALLATION.md-440-444 (1)

440-444: ⚠️ Potential issue | 🟠 Major

Default credentials and secret code published in documentation.

Publishing default credentials (testuser/password123) and the calculator lock code (1234=) in a public repository undermines the security model — especially since the app is designed to be disguised as a calculator for safety reasons. Consider removing these from public-facing docs or at minimum adding a prominent warning to change them immediately.

GOOGLE_MAPS_INTEGRATION.md-136-144 (1)

136-144: ⚠️ Potential issue | 🟠 Major

PII leak: real email address committed in documentation.

Line 138 contains what appears to be a real user's email address (riyarose05@gmail.com). This is personal data that should not be in a public repository. Replace with a generic placeholder like user@example.com.

server/database.js-109-111 (1)

109-111: ⚠️ Potential issue | 🟠 Major

Potential race condition: db is exported before table creation completes.

The Database constructor callback fires asynchronously, and db.run() calls inside it are also async. Any module importing db could issue queries before the schema is ready. Consider serializing table creation with db.serialize().

Proposed fix
   } else {
     console.log('Connected to the SQLite database.');
 
+    db.serialize(() => {
+      db.run('PRAGMA foreign_keys = ON');
+
       // Create Users table
       db.run(`CREATE TABLE IF NOT EXISTS users (...)`);
 
       // ... all other CREATE TABLE statements ...
+    });
   }
server/database.js-11-109 (1)

11-109: ⚠️ Potential issue | 🟠 Major

Foreign key constraints are not enforced by SQLite by default.

SQLite requires PRAGMA foreign_keys = ON to actually enforce foreign key constraints. Without it, all the FOREIGN KEY clauses in your schema are decorative and won't prevent orphaned rows.

Proposed fix
 const db = new verboseSqlite.Database(dbPath, (err) => {
   if (err) {
     console.error('Error opening database:', err.message);
   } else {
     console.log('Connected to the SQLite database.');
+
+    db.run('PRAGMA foreign_keys = ON');
 
     // Create Users table
server/database.js-18-23 (1)

18-23: ⚠️ Potential issue | 🟠 Major

Hardcoded default secret code and plaintext passwords pose critical authentication risks.

The secret_code TEXT DEFAULT '1234=' hardcodes the app's access code in plaintext, compounded by documentation in multiple .md files (REQUIREMENTS.md, INSTALLATION.md, FEATURES.md, API_DOCUMENTATION.md).

More critically, passwords are stored and compared in plaintext throughout the app. The server code (server/index.js) contains a TODO comment // In a real app, hash password here! but no hashing is implemented—neither bcrypt nor other hashing libraries are used. Passwords are inserted directly (line 39) and compared plaintext during login (line 51). This applies to all authentication flows (server/index.js and js/auth.js).

Both issues must be fixed:

  • Remove the default secret_code or store it securely (e.g., environment variables, encrypted)
  • Implement password hashing (bcrypt, argon2, or scrypt) before database insertion and update all login comparisons
API_DOCUMENTATION.md-68-79 (1)

68-79: ⚠️ Potential issue | 🟠 Major

Login response exposes secret_code to the client.

The documented login response includes the user's secret_code field. If this code serves as a secondary authentication factor or emergency access mechanism, returning it on every login response increases the attack surface — any XSS or network sniffing would capture it. Consider omitting it from the default login response and providing a separate, protected endpoint if the user needs to retrieve it.

js/auth.js-17-22 (1)

17-22: ⚠️ Potential issue | 🟠 Major

Plaintext passwords stored in localStorage.

saveUser persists the full user object — including the raw password — into localStorage. The login method then does a plaintext comparison. Even for a client-side simulation, this means every registered user's password is trivially readable by any script on the same origin (or by opening DevTools). If this code ships alongside the real backend auth, users who reuse passwords are at risk.

At minimum, hash passwords before storing (e.g., via the Web Crypto API or a lightweight library), or remove this client-side auth module entirely in favor of the server-side /auth/register and /auth/login endpoints that use bcrypt.

Also applies to: 49-56

sample.html-490-517 (1)

490-517: ⚠️ Potential issue | 🟠 Major

Plaintext passwords stored in localStorage.

Auth.signup stores the raw password in the user object ({ name, email, pass, code, ... }), which is then serialized to localStorage. Anyone with access to the browser's dev tools or any XSS vector can read all credentials. At a minimum, hash passwords before storing (though for a real app, authentication should happen server-side).

server/index.js-410-462 (1)

410-462: ⚠️ Potential issue | 🟠 Major

Like/unlike toggle is not atomic — race condition on concurrent requests.

The check (Line 416), delete/insert (Lines 427/446), and count update (Lines 433/452) are separate, non-transactional operations. Two concurrent like requests from the same user could both pass the check and insert duplicate likes, or both decrement/increment the count. Wrap the operations in a SQLite transaction using db.run('BEGIN TRANSACTION') ... COMMIT.

she_wants_full_app.html-1-594 (1)

1-594: 🛠️ Refactor suggestion | 🟠 Major

This file is nearly identical to sample.html (lines 1–594) — consolidate into a single file.

Maintaining two copies of the same ~600-line file increases the risk of divergence and doubles the effort for any bug fix. Consider keeping only one.

server/index.js-15-27 (1)

15-27: ⚠️ Potential issue | 🟠 Major

CORS allows all origins despite the allowlist.

The else branch on Line 23 calls callback(null, true), meaning blocked origins are still allowed. The logged warning is misleading — nothing is actually blocked.

Proposed fix
         } else {
             console.log('Blocked origin:', origin);
-            callback(null, true); // Allow all for now, restrict in production

Location validation incorrectly rejects valid coordinates.

location.lat === 0 rejects latitude 0 (the equator), and !location.lng rejects longitude 0 (the prime meridian). Both are valid geographic coordinates.

Proposed fix
-    if (!location || location.lat === 0 || !location.lng) {
+    if (!location || typeof location.lat !== 'number' || typeof location.lng !== 'number') {
         return res.status(400).json({ error: 'Valid location is required for pad requests' });

dashboard.html-219-236 (1)

219-236: ⚠️ Potential issue | 🟠 Major

Helper mode toggle does not start/stop the emergency listener.

Emergency.listen is only registered once at page load (Line 226) based on the initial value of user.willingToHelp. If the user toggles helper mode on after loading the page, the listener is never started. Conversely, toggling it off doesn't unsubscribe.

Proposed fix
         function toggleHelperMode() {
             user.willingToHelp = document.getElementById('helperToggle').checked;
             Auth.setCurrentUser(user);

+                Emergency.listen((request) => {

Excessive console.log statements leak PII (user location, user details).

Lines 43, 55–56, 59, 62, 78, and others log the user's GPS coordinates, usernames, and request details to the browser console. In production, this leaks sensitive information. Strip these or gate them behind a debug flag.

This applies broadly across all components in this PR (PadRequest.jsx, SOS.jsx, NearbyRequests.jsx, etc.).

src/components/NearbyRequests.jsx-67-98 (1)

67-98: ⚠️ Potential issue | 🟠 Major

Request is marked as fulfilled before the user actually helps — no undo path.

The API call to mark the request as fulfilled (line 70) happens before Google Maps even opens. If the helper changes their mind, closes the tab, or can't reach the requester, the request is already marked fulfilled with no way to revert. Consider marking it fulfilled only after confirmation of delivery, or adding an "undo" mechanism.

src/components/NearbyRequests.jsx-189-191 (1)

189-191: ⚠️ Potential issue | 🟠 Major

Displaying raw GPS coordinates exposes the requester's exact location.

Showing latitude.toFixed(4) and longitude.toFixed(4) reveals the user's position to ~11 meters accuracy. For a safety-focused app, consider showing only an approximate area (e.g., neighborhood name via reverse geocoding, or a rounded distance) instead of precise coordinates.

src/App.jsx-7-9 (1)

7-9: ⚠️ Potential issue | 🟠 Major

No session persistence — user is lost on page refresh.

user is stored only in React state. Any page refresh will log the user out and lock the app, forcing re-authentication every time. Consider persisting the session (e.g., localStorage, sessionStorage, or a server-side session/token).

Example using localStorage
 function App() {
   const [isLocked, setIsLocked] = useState(true);
-  const [user, setUser] = useState(null);
+  const [user, setUser] = useState(() => {
+    const saved = localStorage.getItem('sheWantsUser');
+    return saved ? JSON.parse(saved) : null;
+  });

   // ...

   const handleLogin = (userData) => {
     setUser(userData);
+    localStorage.setItem('sheWantsUser', JSON.stringify(userData));
     setIsLocked(false);
   };

   const handleLogout = () => {

96-100: ⚠️ Potential issue | 🟠 Major

The "Next" button and hint completely undermine the disguised-calculator privacy feature.

The component's purpose is to appear as a calculator for privacy, yet Line 74 provides a button that directly calls onUnlock('1234=') without any code entry, and Line 99 displays the secret code as a plaintext hint. Anyone glancing at the screen sees both the bypass button and the unlock code, defeating the disguise.

At minimum, remove the hint text. Consider whether the "Next" button should require entering the code rather than bypassing it entirely.

Both handleCreatePost (Line 53-54) and handleAddComment (Line 116-117) send userId and username in the request body. A user can trivially modify the username field (via DevTools or a crafted request) to post as someone else. The server should resolve the username from the authenticated userId instead.

Geolocation fallback sends {lat: 0, lng: 0} — a point in the Gulf of Guinea.

Missing user.id in the dependency array — stale data if user changes.

fetchCycles captures user.id in its closure, but the effect runs only on mount. If the user prop changes (e.g., account switch), the component continues to display the previous user's cycle data.

Proposed fix

Environment variable points to localhost — will not work in production.

Setting VITE_API_URL to http://localhost:3000 during Vercel deployment means the deployed frontend will try to reach localhost in the user's browser, which will fail.

No error handling on CREATE TABLE statements — failures are silently swallowed.

Each db.run() call for table creation lacks a callback. If any CREATE TABLE fails, the error is lost and the app continues with a broken schema. At minimum, pass a callback to log errors.

Example fix pattern
-    db.run(`CREATE TABLE IF NOT EXISTS users (
+    db.run(`CREATE TABLE IF NOT EXISTS users (
       id INTEGER PRIMARY KEY AUTOINCREMENT,
       username TEXT UNIQUE NOT NULL,

Table of Contents anchor links won't resolve due to emoji in headings.

The heading anchors include emoji characters (e.g., ## 🔐 Authentication), but the TOC links use plain fragments like #authentication.

Either remove emoji from headings or update the fragment links to match the generated slugs.

Auth.signup returns { success: true, user: newUser } where newUser still contains the plaintext password. Callers (like signup.html) receive this object and could inadvertently expose it (e.g., logging, DOM injection). Strip the password before returning, similar to what setCurrentUser does.

alert variable shadows window.alert.

Line 128 declares const alert = document.getElementById('alert'), which shadows the built-in window.alert within this function scope. Any future alert("...") call inside handleLogin would throw a TypeError since the variable references a DOM element. Rename to something like alertEl or alertBox.

ensureUniqueCode silently returns a potentially duplicate code after 100 failed attempts.

If all 100 iterations find collisions, the function returns the last generated (non-unique) code without warning. With only 900,000 possible 6-digit codes, this becomes increasingly likely as the user base grows.

Consider warning the user or throwing an error when uniqueness cannot be guaranteed.

Proposed fix
         function ensureUniqueCode() {

event is accessed as an implicit global instead of a function parameter.

setPosts(posts.map(...)) captures the posts value from the render when handleLikePost was created. If a user clicks "like" on multiple posts quickly, earlier state updates may be overwritten.

Use the functional updater form:

The same applies to setPosts in handleAddComment (Line 130).


24-26: Missing fetchPosts in useEffect dependency array — React will warn.

⚠️ Potential issue | 🔴 Critical

Critical: XSS via innerHTML with unsanitized helper.name and helper.dist.

addHelper() injects helper.name and helper.dist directly into HTML via innerHTML. On Line 257-263, Emergency.listen feeds data from external broadcasts into addHelper, so an attacker broadcasting a crafted name like <img src=x onerror=alert(document.cookie)> achieves XSS.

The onclick handler on Line 235 is also injectable — a name containing ' breaks out of the string literal.

Use DOM APIs or textContent instead of innerHTML:

In `@emergency-support.html` around lines 226 - 238, The addHelper function
currently uses innerHTML with unsanitized helper.name and helper.dist and embeds
helper.name into an inline onclick string, enabling XSS; change addHelper to
build DOM nodes with createElement and textContent (e.g., create
div.helper-info, strong, span, and button elements), set the text via
textContent for helper.name and helper.dist, and attach the click behavior to
the button using addEventListener (or pass the helper identifier via a data-
attribute) instead of an inline onclick that interpolates raw values; update
references to helper-item, connect-btn, and connectToHelper accordingly so no
user-controlled string is injected into HTML or event handler attributes.

## 🔒 Security Considerations

### For Production Deployment:

1. **Use HTTPS**: Required for geolocation and secure data
2. **Environment Variables**: Never commit `.env` files
3. **Password Hashing**: Currently uses bcrypt (already implemented)
4. **CORS Configuration**: Restrict to your domain only
5. **Rate Limiting**: Add rate limiting to prevent abuse
6. **Input Validation**: Validate all user inputs (already implemented)
7. **SQL Injection Prevention**: Using parameterized queries (already implemented)

Correct false security claim: passwords are stored in plaintext, not hashed with bcrypt.

Line 335 states "Currently uses bcrypt (already implemented)" but the code explicitly shows the opposite. The signup endpoint (server/index.js:38) contains a comment "In a real app, hash password here!" indicating passwords are stored in plaintext without any hashing. This is a critical security vulnerability that contradicts the documentation.

The parameterized queries claim (line 339) is accurate—the codebase correctly uses ? placeholders with parameter binding arrays to prevent SQL injection.

Update the documentation to accurately reflect that password hashing is not implemented and must be added before production deployment. Remove or qualify the bcrypt claim.

passwords are hashed with bcrypt; update the INSTALLATION.md security section to
remove or negate the "Currently uses bcrypt (already implemented)" statement and
instead state clearly that password hashing is NOT implemented and must be added
before production (e.g., implement bcrypt/argon2 in the signup handler that
currently has the comment "In a real app, hash password here!" in
server/index.js), while keeping the SQL parameterized queries claim intact.

new Function('return ' + calcInput) is equivalent to eval() — arbitrary code execution.

A user (or attacker who can influence calcInput) can execute any JavaScript expression through the calculator display. For example, entering alert(document.cookie) and pressing = would run it. Use a safe math parser instead of new Function.

Safer alternative
         function calculate() {
             // LOGIN CHECK
             if (calcInput.length === 6 && Auth.login(calcInput)) {
                 Navigate('page-welcome');
                 return;
             }
             try {
-                // Safe Math
-                calcInput = new Function('return ' + calcInput.replace('×', '*'))().toString();
+                // Only allow digits, operators, dots, and parentheses
+                if (!/^[\d+\-*/%.()\s]+$/.test(calcInput.replace('×', '*'))) {
+                    throw new Error('Invalid expression');
+                }

             } catch { calcInput = 'Error'; }
             updateDisplay();
         }

A dedicated math expression parser library (e.g., math.js) would be even safer.

In `@sample.html` around lines 527 - 538, The calculate() function uses new
Function('return ' + calcInput...) which is equivalent to eval and allows
arbitrary code execution; replace this with a safe math-expression evaluator
(e.g., integrate math.js or a lightweight parser) and evaluate only numeric
expressions after sanitizing/replacing display symbols (e.g., convert '×' to
'*') and validating the token stream to allow only numbers, parentheses and math
operators; update the try/catch around the evaluation to call the safe parser
(instead of new Function) and set calcInput = 'Error' on parse/eval failures so
the rest of calculate(), updateDisplay(), and the Auth.login/login-check flow
remain unchanged.

The entire HTML document is duplicated — lines 595–1188 are an exact copy of lines 1–594.

This produces invalid HTML: two <!DOCTYPE>, two <html>, two <body> tags, and all element IDs (calc-display, page-calculator, s-name, etc.) are defined twice. Browsers will parse this unpredictably, and getElementById will only find the first occurrence, making the second half's elements unreachable. Remove the duplicate.

Login response leaks the user's plaintext password.

Line 57 returns user: row, which includes the password column from the database. This sends the password back to the client in the JSON response. Additionally, passwords are stored in plaintext (Line 40).

Proposed fix
     db.get(sql, [username, password], (err, row) => {
         if (err) {
             return res.status(500).json({ error: err.message });
         }
         if (row) {
-            res.json({ message: 'Login successful', user: row });
+            const { password, ...safeUser } = row;
+            res.json({ message: 'Login successful', user: safeUser });
         } else {
             res.status(401).json({ message: 'Invalid credentials' });
         }
     });

Passwords should also be hashed (e.g., using bcrypt) before storing in the database.

compares against a hashed password.

this.lastID in the nested callback refers to the wrong db.run invocation.

On Line 493, this.lastID is inside the callback of the updateSql db.run (Line 485), not the insertSql db.run (Line 479). The UPDATE statement doesn't insert a row, so this.lastID will not be the comment's ID.

Replace eval() with a safe math expression parser and clarify the hardcoded unlock code intent.

The eval(display) call in src/components/Calculator.jsx (line 32) is a critical code injection vulnerability. An attacker can input arbitrary JavaScript that will be executed. Replace this with a safe math expression parser like mathjs or a simple tokenizer.

Additionally, "1234=" is hardcoded as a universal unlock code in src/App.jsx (line 13) and src/components/Calculator.jsx (lines 26, 74). While this appears intentional for the disguised calculator design, add a clear comment explaining the security rationale, and consider allowing users to customize this default to prevent unauthorized access if the code becomes widely known.

mathjs evaluate function security alternative eval javascript

💡 Result:

  • Don’t use eval() for user input. It executes arbitrary JavaScript in the caller’s scope and is a well-known injection/XSS sink. [1]
  • mathjs.evaluate() is a security-oriented alternative for math expressions: mathjs parses input into an AST and (in mathjs v4+) explicitly does not use JavaScript eval under the hood, and it blocks access to eval / new Function. [2] It also rejects expressions using blacklisted symbols. [3]
  • Still treat “user-defined expressions” as untrusted code: mathjs notes there can be unknown vulnerabilities and calls out higher-risk functions like import and createUnit (they can change/override functionality). [2]
  • Hardening approach (recommended with mathjs): create your own instance and override/disable dangerous functions (example shown in mathjs security docs disables import, createUnit, and also disables meta-functions like parse/simplify/derivative/evaluate from inside expressions). [2]
  • Isolation for DoS/stability: mathjs warns about heavy expressions (CPU/memory blowups) and suggests running evaluation in a Web Worker / child_process so you can kill runaway jobs. [2]

Other libraries:

  • expr-eval is commonly used as an “eval alternative” for math. [4] But it had a recent critical RCE vulnerability (CVE-2025-12735) affecting versions ≤ 2.0.2, fixed in 2.0.3+ (so if you use it, pin/upgrade and be careful about what you pass in the variables/context object). [5]

Sources:
[1] MDN eval() security warning. [1]
[2] mathjs expression security docs (sandboxing, no eval in v4+, risky functions, hardening + worker isolation). [2]
[3] mathjs parsing/evaluate docs (blacklisted symbols; safer Map scope). [3]
[4] expr-eval repository description (“safer alternative to eval” for math expressions). [4]

Critical: eval() enables arbitrary code execution.

User input is passed directly to eval(display) on line 32 with no sanitization. An attacker or curious user can execute arbitrary JavaScript (e.g., accessing document.cookie, localStorage, or calling fetch). This is a textbook code-injection vulnerability.

Replace eval with a safe math expression parser such as mathjs. Note: mathjs v4+ does not use JavaScript's eval internally, but you should harden the instance by disabling dangerous functions (import, createUnit) as documented in its security guide.

Proposed fix using mathjs

Install mathjs: npm install mathjs

 import React, { useState } from 'react';
 import './Calculator.css';
+import { evaluate } from 'mathjs';
                     } else {
-                        // Try to evaluate as math

⚠️ Potential issue | 🔴 Critical

Race condition: dual timeout can fire sendSOSWithoutLocation twice.

The manual setTimeout (line 26, 5 s) and the Geolocation API's own timeout: 5000 (line 57) create a race. Both can trigger sendSOSWithoutLocation:

  1. Manual setTimeout fires at 5 s → calls sendSOSWithoutLocation.
  2. Geolocation times out → error callback → clearTimeout is a no-op (already fired) → calls sendSOSWithoutLocation again.

This sends two SOS alerts for a single button press. Use a guard flag or remove the manual timeout since the Geolocation API already supports a timeout option.

Proposed fix: remove the redundant manual timeout

Screenshots markdown is invalid (HTML inside alt text).

The current syntax won’t render images reliably. Use standard markdown with the raw image URL.

API section has merged headings/typos that obscure endpoints.

Several headings are merged into routes (e.g., “logineriod”, “ommunity”). This makes the API list ambiguous.
