CVE-2026-106038
Mooncake Store master through 0.3.13.post1 contains a missing authentication vulnerability that allows unauthenticated attackers to force-delete any object via Remove, RemoveByRegex, RemoveAll and BatchRemove on the coro_rpc port.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Mooncake Store master through 0.3.13.post1 contains a missing authentication vulnerability that allows unauthenticated attackers to force-delete any object via Remove, RemoveByRegex, RemoveAll and BatchRemove on the coro_rpc port. Attackers can send forged requests with the force flag set to bypass lease checks, wipe keys matching any regex, or clear the entire store, causing cache loss and request failures.
