Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Asynchronous authorization promises were not correctly returned to Koa's middleware chain, causing the framework to proceed to the controller action before the security check resolved, effectively bypassing authorization.
Auth Bypass: Errors thrown during synchronous authorization checker evaluation were poorly handled, risking authorization bypasses if security guards were skipped or crashed silently during the middleware cycle.
Auth Bypass: Controller class-level @Authorized decorators failed to inherit correctly down to individual action methods, leaving endpoints exposed if they lacked explicit method-level authorization.
