PR Summary
This PR temporarily disables CSRF protection in the Apple authentication flow, which is a critical security concern that needs immediate attention.
- SECURITY RISK: Commenting out state validation in
frontend/src/components/AppleAuthProvider.tsxremoves protection against CSRF attacks - State parameter is still stored but not validated, leaving the authentication flow vulnerable to session riding attacks
- Root cause of state validation issues should be investigated and fixed properly instead of disabling protection
- Consider implementing alternative CSRF mitigation if state validation is problematic

Security Risk: CSRF protection disabled in second location
This is the second instance where state validation has been commented out. Both locations need to be fixed to restore the security protection.
For consistency, apply the same changes here:
+ // TODO: Fix state validation later - TICKET-123
+ console.warn("[Apple Auth] SECURITY WARNING: CSRF protection disabled - state validation skipped");
// const storedState = sessionStorage.getItem("apple_auth_state");
// if (state !== storedState) {
// throw new Error("Invalid state parameter - potential CSRF attack");
// }📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In frontend/src/components/AppleAuthProvider.tsx around lines 292 to 296, the
state validation code that protects against CSRF attacks is commented out. To
fix this, uncomment the lines that retrieve the stored state from sessionStorage
and compare it with the current state parameter. If they do not match, throw an
error indicating a potential CSRF attack. This will restore the necessary
security check consistently in both locations.

Security Risk: CSRF protection disabled
Commenting out the state validation code disables a critical security protection against Cross-Site Request Forgery (CSRF) attacks. While the TODO comment indicates this is temporary, the absence of validation makes the authentication flow vulnerable to potential attacks.
I recommend:
- Add a specific timeline or ticket reference to the TODO comment
- Add a warning log when this validation is skipped:
+ // TODO: Fix state validation later - TICKET-123
+ console.warn("[Apple Auth] SECURITY WARNING: CSRF protection disabled - state validation skipped");
// const storedState = sessionStorage.getItem("apple_auth_state");
// if (state !== storedState) {
// throw new Error("Invalid state parameter - potential CSRF attack");
// }Security Risk: Re-enable CSRF State Validation
Commenting out the state check in frontend/src/components/AppleAuthProvider.tsx removes critical CSRF protection from the Apple sign-in flow. Without comparing the returned state against the stored apple_auth_state, attackers can forge authentication requests.
Please address this by:
- Referencing a tracking ticket and estimated timeline in the TODO (e.g.
TODO: Fix state validation later – TICKET-123). - Emitting a clear warning when state validation is skipped.

In frontend/src/components/AppleAuthProvider.tsx around lines 211 to 215, the
state validation code for CSRF protection is commented out, disabling a critical
security check. To fix this, update the TODO comment to include a specific
ticket reference and timeline (e.g., "TODO: Fix state validation later –
TICKET-123"). Additionally, add a warning log statement that clearly indicates
when the state validation is skipped, so it is visible in logs and can be
monitored until the validation is re-enabled.
