Technical Analysis
CVE-2026-106038 describes a missing authentication vulnerability in kvcache-ai Mooncake Store master up to version 0.3.13.post1. Unauthenticated attackers can exploit this flaw by sending forged requests with the force flag set to bypass lease checks and invoke Remove, RemoveByRegex, RemoveAll, and BatchRemove functions on the coro_rpc port. This allows attackers to delete specific keys, keys matching regex patterns, or clear the entire cache store, resulting in cache loss and potential request failures.
Potential Impact
The vulnerability allows unauthenticated attackers to forcibly delete cached objects, causing cache loss and disruption of service due to request failures. This can degrade application performance and availability relying on the cache.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the coro_rpc port to trusted entities only to mitigate unauthorized deletion attempts.
