Prior to 0.32.0, an authenticated caller can place forged shared-memory address and monotonic_id values in public multimodal features.kwargs_data. In scale-out deployments with shared-memory multimodal caching enabled, workers trust those values and pass attacker-selected bytes to pickle.loads(), allowing arbitrary Python execution even when insecure serialization is disabled. This issue is fixed in version 0.32.0.","categories":["Unclassified"],"product":"vllm","vendor":"vllm-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115912","source_modified_at":"2026-10-26T16:54:00.643Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"vllm","vendor":"vllm-project","versions":[{"version":"< 0.32.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T16:54:00.643Z","modified_at":"2026-10-26T16:54:00.643Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115912","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T16:54:00.643Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-6757-hggm-hp2w","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/pull/59357","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/commit/3d5625cc3c2474994107047d7a6ecb8e4008f9b0","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/vllm-project/vllm/releases/tag/v0.32.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T16:54:00.643Z","content_hash":"978f6fb8f4305fb407cc6078b92ab908885421a7d29d1e2716f7ccc197a9e89d"}}
