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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-502"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ModelTC/LightLLM","tags":[]},{"url":"https://github.com/ModelTC/LightLLM/issues/1629","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/api_lightllm.py#L37-L43","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/core/objs/sampling_params.py#L356-L357","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/router/model_infer/infer_batch.py#L484-L485","tags":[]},{"url":"https://www.vulncheck.com/advisories/lightllm-through-1.2.0-unauthenticated-dos-via-pd-kv-trans-params-deserialization","tags":[]}],"exploitRefs":[{"url":"https://github.com/ModelTC/LightLLM","tags":[]},{"url":"https://github.com/ModelTC/LightLLM/issues/1629","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/api_lightllm.py#L37-L43","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/core/objs/sampling_params.py#L356-L357","tags":[]},{"url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/router/model_infer/infer_batch.py#L484-L485","tags":[]}],"hasPoc":true,"ai":null}
