CVE-2026-111160 Details
Description
LightLLM through 1.2.0 contains a denial of service vulnerability that allows unauthenticated attackers to crash the inference worker by supplying the internal pd_kv_trans_params field to the /generate endpoint. Attackers can send a single request whose parameters cause pickle.loads to fail in InferSamplingParams, killing the inference thread while /health stays up and all later requests hang until restart.
A denial-of-service vulnerability has been identified in LightLLM versions through 1.2.0. This issue allows unauthenticated attackers to disrupt the inference worker by sending requests to the /generate endpoint with manipulated pd_kv_trans_params. The deserialization of these parameters causes the inference thread to crash, while the /health endpoint continues to report a healthy status. As a result, subsequent requests are stalled until the node is manually restarted.
