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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.70%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
