Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inconsistent identity lookup keys and uninitialized state reads in cookie-based session handling allowed attackers to spoof session parameters and bypass credentials verification entirely. Security relies on a stable, random identifier mapped accurately to the target user profile.
Auth Bypass: Improper handling of JWT signature decoding exceptions and missing payload validation enabled attackers to present malformed or modified tokens to force a valid login state.
Auth Bypass: OAuth or guest sign-in mechanisms that failed to verify whether a registration identity already existed could overwrite or hijack pre-existing application user accounts.
