CVE-2026-106039
MediumCVSS 6.5Summary
Mooncake Store through 0.3.13.post1 has a missing authorization vulnerability allowing unauthenticated attackers to create, steal, and falsely complete replication tasks via the coro_rpc port. Attackers can invoke CreateCopyTask, CreateMoveTask, FetchTasks, and MarkTaskToComplete with victim client UUIDs disclosed by QueryTask to hijack task queues and record replication that never occurred.
Risk Assessment
Attackers can take over replication tasks, potentially leading to data integrity compromise or system disruption.
Recommendation
Update Mooncake Store to a version newer than 0.3.13.post1. Additionally, implement authorization mechanisms for the coro_rpc port.

See all- CVE-2026-106041Medium
Mooncake Store through 0.3.13.post1 has a missing authorization vulnerability allowing unauthenticated attackers to inject completed LOCAL_DISK replicas via NotifyOffloadSuccess RPC. Attackers can mount a local disk segment with a self-chosen client UUID, then attach replicas pointing at attacker-controlled endpoints to serve poisoned disk-tier reads and fake key existence.
- CVE-2026-106040High
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.
- CVE-2026-106038High
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.
