Misaka Danmu Server through 2.8.9 contains an authentication bypass vulnerability that allows unauthenticated attackers to write arbitrary configuration keys via the unprotected POST /api/ui/config-history/rollback endpoint. Attackers can set the ipWhitelist key to their own /32 address, or alter trustedProxies and webhookApiKey, to access every protected endpoint as the administrator.
