Description
Misaka Danmu Server through 2.8.9 contains a missing authentication vulnerability that allows unauthenticated attackers to access audit, diagnostics, data-check, scan-index and health routes under /api/ui lacking the get_current_user dependency. Attackers can read audit logs with login IPs, server logs and environment paths, delete episode rows, clear media-server mappings, and wipe audit history.
