B3log Symphony is a Java-based community platform (forum, Q&A, blog) that requires administrative authentication for sensitive operations.

## Technical details

The PermissionMiddleware improperly permits routes lacking permission.rule.url entries, allowing unauthenticated access to privileged endpoints. Attackers can directly invoke /admin/report/ignore/{reportId}, /admin/tags/remove-unused, and /admin/user/{userId}/init-point without authentication. This is a broken access control vulnerability in the routing/middleware layer affecting administrative functions.
