The core functionality run_server_loop() calls the function _make_handler_coro(), which directly uses cloudpickle.loads() on received messages without any sanitization. This can result in remote code execution by deserializing malicious pickle data.\n\n## Affected packages\n\n- `vllm <= 0.6.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.3,"exploitation":0,"ransomware":0},"changes":[]}
