Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Two-factor authentication (2FA) could historically be bypassed when users authenticated using their email addresses rather than their usernames, as well as via unrated brute-force attempts on the verification endpoint.

Deserialization of Untrusted Data: The application used unsafe PHP unserialize() calls on user-supplied cookie and session data, creating high-risk vectors for PHP Object Injection and Remote Code Execution.

Open Redirect: Inadequate local URL validation on post-login and post-reset parameters allowed attackers to redirect authenticated victims to external malicious domains.
