Summary

Mooncake through 0.3.13.post1 lacks authentication on its Store REST service, which binds to 0.0.0.0 and accepts requests on any route without checks (CWE-306). An unauthenticated remote attacker 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 segments that the attacker describes.
