Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Google OAuth authentication was susceptible to account hijacking and bypasses due to a lack of signature and claim verification of incoming identity tokens against Google's JWKS, as well as tracking users via mutable emails rather than immutable subject identifiers.
Auth Bypass: Role delegation and assignment workflows failed to enforce administrative boundary constraints properly, potentially permitting lower-privileged users to escalate privileges by assigning or modifying roles with permission scopes exceeding their own.
Auth Bypass: Token verification mechanisms permitted authorization bypasses by calling next() instead of terminating on failed validations or missing actor-identity/entity identifiers.
