# Misaka Danmu Server: unauthenticated admin routes delete data, wipe audit logs

Misaka Danmu Server through 2.8.9 exposes audit, diagnostics, data-check, scan-index and health routes under /api/ui without the authentication check. An unauthenticated attacker can read audit logs with login IPs, server logs and environment paths, delete episode rows, clear media-server mappings and wipe audit history.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version is `2.8.9` or earlier.
- Request the /api/ui audit, diagnostics or health routes without credentials and see whether they return data.

## From the sources

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.
