Overview
vllm is an A high-throughput and memory-efficient inference and serving engine for LLMs
Affected versions of this package are vulnerable to Improper Check or Handling of Exceptional Conditions via incomplete kv_transfer_params dictionary entries in the NIXL connector's metadata handling for prefill/decode disaggregated deployments. An attacker can send requests with missing keys in the kv_transfer_params dictionary to trigger an uncaught KeyError in EngineCore scheduling, causing the decode engine to terminate and making all routed requests fail until a manual restart is performed.
