Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
LMDeploy versions from 0.9.2 before 0.16.0 are vulnerable when PD-disaggregation/DistServe is enabled on the PyTorch backend. An attacker who can reach the DistServe API can point the server at a malicious ZeroMQ endpoint, which can run arbitrary code as the serving process because of pickle deserialization; no API key is required unless the operator configured one. Upgrade LMDeploy to 0.16.0 or later; until then, keep untrusted clients away from the /distserve endpoints and enable API-key authentication.
