Mooncake through 0.3.13.post1 contains a missing authentication vulnerability in the Store REST service, which binds to 0.0.0.0 without authentication on any route. Unauthenticated attackers can call routes such as /api/get, /api/put, /api/remove_all and /api/mount to read cached KV data with user prompts, inject or delete objects, and mount attacker-described segments.
