Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Authentication Bypass: An anonymous user session was incorrectly treated as an authenticated principal, which skipped the required authentication step and attempted to attach a social identity connection to an unauthenticated session. This exposes the application to unauthorized account linking.
Open Redirect: Miscalculation of OAuth2 redirection targets when deployed behind proxy servers can occur if X-Forwarded headers are not correctly handled. This leads to issues generating host URLs or potential open redirection vectors if internal request details are untrusted.
