Description

Mooncake Store master through 0.3.13.post1 contains a missing authorization vulnerability that allows unauthenticated attackers to erase any object's disk replica via EvictDiskReplica and BatchEvictDiskReplica. Attackers reaching the coro_rpc master port can evict DISK replicas across all tenants, deleting objects whose only remaining replica is on disk.
