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.","categories":["Unclassified"],"product":"LightLLM","vendor":"ModelTC","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-111160","source_modified_at":"2026-10-21T01:24:32.515Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"LightLLM","vendor":"ModelTC","versions":[{"version":"0","lessThanOrEqual":"1.2.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00418,"percentile":0.35035,"score_date":"2026-10-23"},"published_at":"2026-10-15T18:57:48.390Z","modified_at":"2026-10-21T01:24:32.515Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-111160","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T01:24:32.515Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-111160","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/ModelTC/LightLLM/issues/1629","tags":["issue-tracking","exploit"]},{"source":"CVE List","url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/api_lightllm.py#L37-L43","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/core/objs/sampling_params.py#L356-L357","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/ModelTC/lightllm/blob/v1.2.0/lightllm/server/router/model_infer/infer_batch.py#L484-L485","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/ModelTC/LightLLM","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/lightllm-through-1.2.0-unauthenticated-dos-via-pd-kv-trans-params-deserialization","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-21T01:24:19.467366Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-21T01:24:32.515Z","content_hash":"737b635e1364b8c53a962faf776df05aee22c175e986608bfeda9e4693a267b4"}}
