Technical details

A missing authentication vulnerability in Mooncake Store versions through 0.3.13.post1 allows unauthenticated remote attackers to invoke deletion operations (Remove, RemoveByRegex, RemoveAll, BatchRemove) on the coro_rpc port. Attackers can set a force flag to bypass lease checks, delete keys matching arbitrary regex patterns, or clear the entire data store. Network access to the coro_rpc port is the only prerequisite.
