Recurring patterns

Auth Bypass: Authorization checks on nested route segments previously only validated the leaf segment, allowing sub-route security bypasses. Security policies must ensure intersection-based authority validation across all matched route segments.

Auth Bypass: Route authority matching suffered from prefix-matching vulnerabilities where shorter parent route definitions could mask more restrictive child-route definitions. Strict pathRegexp matching with trailing slash verification is required.

Auth Bypass: Fallback mechanisms historically granted 'admin' privileges by default when no explicit authority was configured, leading to immediate privilege escalation.
