CVE-2026-106038: Mooncake Store through 0.3.13.post1 Unauthenticated Object Deletion via Remove RPCs
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 cororpc 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.

Frequently Asked Questions
Which deployments are exposed?
Mooncake Store master through 0.3.13.post1 is affected if its coro_rpc port is reachable by an attacker. The vulnerable removal RPCs do not require authentication.
What does an attacker need to exploit this issue?
An attacker needs network access to the coro_rpc port and can send forged Remove, RemoveByRegex, RemoveAll, or BatchRemove requests. No credentials or user interaction are required.
What is the practical impact of successful exploitation?
An attacker can force-delete individual objects, objects matching a chosen regular expression, or the entire store. This can cause cache loss and request failures.
Why does the force flag matter?
Forged requests can set the force flag to bypass lease checks, allowing deletion even when lease protections would otherwise apply.
