## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-w5f2-9q9c-ff4h. This link is maintained to preserve external references. ## Original Description LMCache multiprocess mode, also called distributed mode, opens an unauthenticated ZeroMQ ROUTER so worker processes can register and share KV cache blocks. Messages on that socket are msgpack. Extension code 1 is passed to DeviceIPCWrapper.Deserialize, which calls pickle.loads, while the server is still decoding request arguments and before the handler runs. A single unauthenticated ZMQ DEALER message to the transport port (default 5555) therefore executes code as the user the LMCache process runs as. Official container images run that process as root. The transport binds to localhost unless the operator sets a routable address with --host, which is how multi-node deployments let peers connect.

What to do

Three questions, each answered from this record only. Confirm the vendor advisory before you patch.

Should you patch?

Exploitation likelihood is not on this record for GHSA-vv44-hjm2-qw2f. A missing EPSS score is not a low risk. Compare Duplicate Advisory: Remote code with the linked advisory before you change production.

Which versions are affected?

Compare what you have installed with 0.3.10, 0.3.10.post1, 0.3.10.post2, from 0.3.9. Compare the installed version with the linked vendor advisory before you change production.
