Recurring patterns

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

Auth Bypass: Insecure token processing where token signatures were either not verified (using JWT.decode) or verified in an incorrect sequence relative to user profile retrieval. This allowed potential token forgery or misuse of custom authentication headers.

Auth Bypass: Bypasses in route authentication due to missing or misconfigured validation constraints, such as unexecuted Joi validation functions or missing required fields on critical user identifiers.

Auth Bypass: Flawed user registration logic that inverted email checks and allowed role self-assignment, potentially allowing attackers to register with elevated privileges.
