1-7: 💡 Codebase verification

Example should demonstrate optional fields for better coverage

The example can be enhanced by showing the following optional spec fields:

  • adminType: Can be 'serviceAccount' or 'user' (defaults to 'user')
  • insecureSkipVerify: Controls SSL certificate verification
  • caCert: For defining custom CA certificate using ConfigMap or Secret

Example locations that need attention:

  • packages/system/keycloak-operator/charts/keycloak-operator/_crd_examples/clusterkeycloak.yaml
🔗 Analysis chain

Verify completeness of spec fields

Let's verify if there are any additional optional fields in the spec that should be demonstrated in this example.


Let me check the CRD definition file to verify the available spec fields.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for the CRD definition to verify all available spec fields
ast-grep --pattern 'kind: CustomResourceDefinition
  $$$
  spec:
    $$$
    names:
      kind: ClusterKeycloak
    $$$'

# Search for other example usage patterns
rg -l 'kind:\s+ClusterKeycloak' --type yaml

Length of output: 640


Script:

#!/bin/bash
# Get the content of the CRD file to examine the spec fields

packages/system/keycloak-operator/Makefile (1)

3-7: 🛠️ Refactor suggestion

Enhance the update target with version pinning and error handling

While the update target successfully manages the Keycloak operator chart, it could benefit from several improvements:

  1. Missing .PHONY declaration
  2. No version pinning for the helm chart
  3. No error handling for the commands
  4. No verification of successful chart download

Consider applying these improvements:

+.PHONY: update
+
 update:
-	rm -rf charts
-	helm repo add epamedp https://epam.github.io/edp-helm-charts/stable
-	helm repo update epamedp
-	helm pull epamedp/keycloak-operator --untar --untardir charts
+	rm -rf charts || exit 1
+	helm repo add epamedp https://epam.github.io/edp-helm-charts/stable || exit 1
+	helm repo update epamedp || exit 1
+	helm pull epamedp/keycloak-operator --version 1.0.0 --untar --untardir charts || exit 1
+	[ -d "charts/keycloak-operator" ] || (echo "Chart download failed"; exit 1)

Additionally, consider adding a version variable at the top of the Makefile:

KEYCLOAK_OPERATOR_VERSION ?= 1.0.0

And then use it in the helm pull command:

helm pull epamedp/keycloak-operator --version $(KEYCLOAK_OPERATOR_VERSION) --untar --untardir charts || exit 1
packages/system/keycloak-operator/charts/keycloak-operator/_crd_examples/clusterkeycloakrealm.yaml (1)

6-6: 💡 Codebase verification

The ClusterKeycloak reference needs to be updated

The ClusterKeycloakRealm example references 'clusterkeycloak-sample', but the corresponding ClusterKeycloak example is named 'keycloak-sample'. Since clusterKeycloakRef is a required field as per the CRD, this mismatch needs to be fixed by updating either:

  • The clusterKeycloakRef in clusterkeycloakrealm.yaml to "keycloak-sample", or
  • The name in clusterkeycloak.yaml to "clusterkeycloak-sample"
🔗 Analysis chain

Verify the referenced ClusterKeycloak resource

The spec references a ClusterKeycloak named 'clusterkeycloak-sample' which must exist for this realm to be created successfully.


Let me check the content of the referenced ClusterKeycloak example to verify if it matches.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Check if there's a corresponding example for the referenced ClusterKeycloak
fd clusterkeycloak -t f . packages/system/keycloak-operator/charts/keycloak-operator/_crd_examples/

# Check if the CRD defines this field as required

6-8: 💡 Codebase verification

Based on the search results showing no validation logic for realm references in either CRDs or Go files, I can now provide a final response:

Add validation for realm references

The realmRef structure in KeycloakRealmRoleBatch lacks validation. This could lead to runtime errors if:

  • Referenced realm doesn't exist
  • Realm name contains invalid characters
  • Kind is incorrect

Add OpenAPI validation in the CRD to ensure:

  • name field is required and follows DNS subdomain naming convention
  • kind field is required and equals "KeycloakRealm"
🔗 Analysis chain

Verify realm reference validation

The realmRef structure looks correct, but ensure the operator validates:

  1. The referenced realm exists
  2. The realm name follows Keycloak naming conventions

Let me try a different search pattern to find validation logic for realm references.


Let me try one more search to specifically look for CRD validation related to realm references in the keycloak operator.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash

10-16: ⚠️ Potential issue

Security: Replace default credentials in example

Using admin/admin as example credentials, even in sample configurations, might lead to security issues if copied to production environments.

Consider:

  1. Using more complex example credentials
  2. Adding a clear warning comment about changing credentials
  3. Using placeholder values like <your-secure-username> and <your-secure-password>
 apiVersion: v1
 kind: Secret
 metadata:
   name: keycloak-access
 data:
-  username: YWRtaW4=
-  password: YWRtaW4=

packages/system/keycloak-operator/charts/keycloak-operator/_crd_examples/keycloakrealmuser_password.yaml (1)

19-21: 💡 Codebase verification

Secret handling needs additional documentation and examples

Based on the verification results:

  • While there are examples of secret creation for Keycloak and client credentials, there's no example for the passwordSecret in the context of KeycloakRealmUser
  • The documentation shows basic secret usage but lacks password policy requirements and best practices
  • No explicit documentation about secret access permissions or prerequisites

Recommendations:

  • Add an example YAML showing the creation of the referenced existing-k8s-secret for KeycloakRealmUser
  • Document password policy requirements and secret access prerequisites in the README
  • Include a section about RBAC considerations for secret access
🔗 Analysis chain

Security consideration: Review password secret handling

The configuration references an external Kubernetes secret for password storage, which is a good security practice. However:

  1. Ensure the secret is created before applying this resource
  2. Consider documenting password policy requirements
  3. Verify secret access permissions

Let me check the content of the found files to better understand the secret handling and documentation.

4-4: 🛠️ Refactor suggestion

Remove duplicate name field

The component name is redundantly specified in both metadata.name and spec.name. This could lead to confusion and maintenance issues.

  name: component-sample
spec:
  realmRef:
    name: keycloakrealm-sample
    kind: KeycloakRealm

6-8: 💡 Codebase verification

Update the realm reference to match the example realm

The referenced realm name "realm" in the identity provider example doesn't match any existing realm in the examples. The KeycloakRealm example uses keycloakrealm-sample as the metadata name. Update the realm reference to match this example:

realmRef:
  kind: KeycloakRealm
  name: keycloakrealm-sample
🔗 Analysis chain

Verify the referenced KeycloakRealm existence

The spec references a KeycloakRealm named "realm" which seems like a generic name. Since this is an example, consider using a more descriptive name like "example-realm" or "instagram-realm" to better illustrate the relationship.

16-25: ⚠️ Potential issue

Review event configuration for security compliance

Several concerns with the current event configuration:

  1. Admin events are enabled but details are disabled, which might affect audit capabilities
  2. Only two event types are enabled, potentially missing critical security events
  3. Event expiration of 15000 seconds (≈4.17 hours) might be too long for sensitive environments

Consider these adjustments:

Review token lifecycle configuration

The current configuration sets all token lifespans to 300 seconds (5 minutes). Consider differentiating lifespans based on token type and usage:

  • Access tokens: 5-15 minutes
  • Refresh tokens: 24-48 hours
  • Action tokens: Based on specific use cases (e.g., longer for email verification)

Consider adjusting token lifespans:

   tokenSettings:
     accessTokenLifespan: 300
     accessCodeLifespan: 300
-    accessToken: 300
+    accessToken: 900  # 15 minutes

Enhance password policy security

While the current password policies include expiration and length requirements, consider adding these recommended security measures:

  • Increase minimum length to 12 characters
  • Add complexity requirements (uppercase, lowercase, numbers, special characters)
  • Add maximum password age
  • Add password history

Consider adding these additional password policies:

Review security implications of broad web origins and redirect URIs

  1. The /* web origin is overly permissive and could pose security risks
  2. Local development redirect URIs should not be present in production configurations

1-25: ⚠️ Potential issue

Security concern: Authentication bypass risk with ALTERNATIVE requirements

The current configuration allows users to authenticate either via cookies OR identity provider redirect. This could potentially allow users to bypass the intended authentication flow if the cookie authentication is not properly secured.

Consider:

  1. Changing the requirement levels to be more strict (e.g., "REQUIRED" for critical steps)
  2. Reviewing if both authentication methods should really be alternatives

Additionally:

  • The name "Demo" suggests this might be example code. Ensure this is not used in production.
  • Consider adding more specific description beyond "Example of KeycloakAuthFlow"

Enhance X509 authentication security configuration

The X509 client certificate authentication is configured with an ALTERNATIVE requirement, which might not provide sufficient security for certificate-based authentication.

Consider:

  1. Changing the requirement to "REQUIRED" for certificate authentication
  2. Adding certificate validation configurations
  3. Specifying accepted certificate authorities and validation rules
     - authenticator: "auth-x509-client-username-form"

Fix priority conflict and requirement levels in OTP flow

There are several issues with the Conditional OTP flow configuration:

  1. Both executions have the same priority (0), which could lead to unpredictable execution order

Security: Update default secret value

The secret contains a weak default value ('password' in base64). This poses a security risk if used in production.

Recommendations:

  1. Remove the default value completely and document that it needs to be set
  2. Or use a reference to an external secret management system
  3. Ensure the actual secret is never committed to version control

134-140: ⚠️ Potential issue

Review the dependency configuration for keycloak-operator

The operator's dependency on keycloak seems counterintuitive. Typically, operators should be installed before the resources they manage to ensure proper initialization and management capabilities. This dependency might cause initialization problems or circular dependencies.

Consider removing the dependency on keycloak to align with the pattern seen in other operators in this file (e.g., postgres-operator, redis-operator) which don't depend on their managed resources.

Apply this diff to fix the dependency configuration:

 - name: keycloak-operator
   releaseName: keycloak-operator
   chart: cozy-keycloak-operator
   namespace: cozy-keycloak
   optional: true
-  dependsOn: [keycloak]
+  dependsOn: []

Then, consider updating the keycloak entry to depend on the operator instead:

 - name: keycloak
   releaseName: keycloak

   namespace: cozy-keycloak
   optional: true
-  dependsOn: [postgres-operator]

Enhance secret documentation.

The secret field documentation should specify the expected format and required keys within the secret.

Add detailed documentation:

  secret:
-   description: Secret is a secret name which contains admin credentials.
+   description: |-
+     Secret is a secret name which contains admin credentials.
+     The secret must contain the following keys:

1-138: 💡 Codebase verification

RBAC rules are properly defined, but additional security controls recommended

The verification shows that RBAC rules are properly defined in both operator_role.yaml and clusterrole.yaml with appropriate permissions for managing keycloakrealmroles. However, some security enhancements are recommended:

  • The CRD should implement validation rules for security-sensitive fields like composite and composites to prevent privilege escalation
  • Consider adding OpenAPI v3 schema validations for attributes to restrict potential malicious input
  • No built-in audit logging was found for role changes - consider implementing audit annotations

Let me explain why this is categorized as :

  1. The RBAC configuration is properly defined with necessary permissions
  2. However, the CRD lacks important security validations that could prevent misuse
  3. The absence of audit logging for role changes in a security-sensitive CRD is a notable gap
🔗 Analysis chain

Verify RBAC and security implications

Since this CRD manages Keycloak roles, which is security-sensitive:

  1. Ensure proper RBAC rules are defined for this CRD
  2. Consider adding validations for security-sensitive fields
  3. Verify audit logging for role changes
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

# Check for audit logging configuration

1-6: 💡 Codebase verification

⚠️ Potential issue

Fix indentation in labels section

The indentation in operator_role.yaml is inconsistent with the rest of the chart's resources. All other Kubernetes resources in the chart use 4 spaces indentation for the labels section, while this file uses 6 spaces. Apply this change:

  labels:
-      {{- include "keycloak-operator.labels" . | nindent 4 }}
+    {{- include "keycloak-operator.labels" . | nindent 4 }}
🔗 Analysis chain

Fix indentation in labels section.

The labels section has incorrect indentation. It should be 4 spaces instead of 6.

Apply this diff to fix the indentation:

  labels:
-      {{- include "keycloak-operator.labels" . | nindent 4 }}
+    {{- include "keycloak-operator.labels" . | nindent 4 }}

81-100: ⚠️ Potential issue

Consider enforcing the use of passwordSecret over direct password field

While the documentation recommends using passwordSecret, the direct password field still allows storing sensitive data in the CR spec, which is less secure because:

  1. CR specs are often stored in git repositories
  2. CRs are readable by anyone with basic cluster permissions
  3. Passwords in CRs appear in logs and events

Consider one of these approaches:

  1. Mark the password field as deprecated
  2. Add validation to prevent both password and passwordSecret being set simultaneously
  3. Add a warning event when password field is used
              password:
                description: Password is a user password. Allows to keep user password
                  within Custom Resource. For security concerns, it is recommended
                  to use PasswordSecret instead.

91-101: ⚠️ Potential issue

Review security implications in KeycloakClient example

The example contains potentially sensitive configuration:

  1. Empty secret field could be misleading
  2. Hardcoded URL (example.com) should be replaced with a placeholder or documentation reference

Consider updating the example:

     spec:
       advancedProtocolMappers: true
       clientId: agocd
       directAccess: true
       public: false
-      secret: ''

🛠️ Refactor suggestion

Add error handling for ConfigMap lookup and value validation

The configuration retrieval lacks error handling for scenarios where the ConfigMap or required data might be missing.

Consider adding validation using Helm's required function:

-{{- $cozyConfig := lookup "v1" "ConfigMap" "cozy-system" "cozystack" }}
-{{- $host := index $cozyConfig.data "root-host" }}
-{{- $apiServerAdress := index $cozyConfig.data "api-server-adress" }}
+{{- $cozyConfig := lookup "v1" "ConfigMap" "cozy-system" "cozystack" | required "ConfigMap 'cozystack' not found in namespace 'cozy-system'" }}
+{{- $host := index $cozyConfig.data "root-host" | required "root-host is required in cozystack ConfigMap" }}
+{{- $apiServerAdress := index $cozyConfig.data "api-server-adress" | required "api-server-adress is required in cozystack ConfigMap" }}
