Date of Scan: 2026-02-27 Scope: antigravity_phone_chat core server and client files. Standard: OWASP Top 10

Status: Warning

• Observation: server.js correctly relies on .env for APP_PASSWORD and SESSION_SECRET.
• Finding: Hardcoded fallback values ('antigravity' and 'antigravity_secret_key_1337') exist in server.js. While the system enforces strict cookie/password requirements for remote connections, relying on these default literals if a .env file is missing can pose a deterministic attack vector if the server relies solely on them in Web Mode.
• Resolution/Mitigation: The launcher.py and bash scripts correctly enforce .env generation before launching, significantly reducing the likelihood of falling back to default literals.

Status: Passed

• Observation: app.js relies heavily on innerHTML for state mirroring (chatContent.innerHTML = data.html).
• Finding: Because data.html is strictly composed of clones from the desktop application's DOM (via Chrome DevTools Protocol), the injection risk is identical to the underlying Antigravity app.
• Additionally: The chat history extraction (server.js) strictly utilizes a custom escapeHtml() utility to sanitize raw IDE innerText before it is transmitted back to the client interface, preventing standard string-based XSS attacks on the history view.

Status: Passed

• Observation: The express server enforces an implicit Zero-Trust policy on external IPs but implements an "Always Allow" policy for local network requests.
• Finding: API routes are guarded securely and httpOnly signed cookies are deployed.
• Note: The bypass LAN auth design represents a conscious usability tradeoff. Access implies physical network presence.

Status: Passed

• Observation: Core dependencies (express, ws, cookie-parser, dotenv) are cleanly defined without bloated sub-dependencies.
• Finding: No immediate critical supply chain vulnerabilities observed.

Conclusion: The repository is in strong standing. The underlying architecture explicitly proxies to a sandboxed desktop DOM environment, dramatically reducing server-side execution risks.
