Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inconsistencies and logical flaws in how token state and user roles are compared on subsequent requests can prevent the system from detecting changes in a user's roles, resulting in authorization bypass or failure to invalidate stale sessions.
User Enumeration: Discrepancies in the exceptions thrown or processed during authentication failures (e.g., distinguishing between inactive users and wrong credentials) allow attackers to enumerate valid usernames.
Denial of Service: Passing unexpected non-string parameters (like arrays) into CSRF token checks triggers unhandled PHP TypeErrors, causing request processing to crash.
