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.","state":0,"publishedAt":"2026-10-15T18:57:48.39+00:00","modifiedAt":"2026-10-21T01:24:32.515+00:00","affected":[{"ecosystem":"Vendor product","name":"LightLLM","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ModelTC\",\n                    \"product\": \"LightLLM\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"1.2.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"packageURL\": \"pkg:github/ModelTC/lightllm\",\n                    \"repo\": \"https://github.com/ModelTC/lightllm\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/ModelTC/LightLLM/issues/1629","https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/api_lightllm.py#L37-L43","https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/core/objs/sampling_params.py#L356-L357","https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/router/model_infer/infer_batch.py#L484-L485","https://github.com/ModelTC/LightLLM","https://www.vulncheck.com/advisories/lightllm-through-1.2.0-unauthenticated-dos-via-pd-kv-trans-params-deserialization"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111160","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111160","identifiers":["CVE-2026-111160"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
