Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: A pre-save database hook previously granted default administrator privileges to users registering with empty roles, exposing a severe privilege escalation vector in the registration flow.
Auth Bypass: Authorization middleware failed to terminate unauthorized API requests immediately, instead performing a redirection that allowed requests to proceed past intended security bounds.
