LightLLM through 1.2.0 Unauthenticated DoS via pd_kv_trans_params Deserialization

Published Oct 15, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
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.
