{"id":"CVE-2026-115912","aliases":["GHSA-6757-hggm-hp2w"],"url":"https://o3.security/vulnerability/CVE-2026-115912","summary":"vLLM: Public multimodal SHM handle forgery reaches worker-side `pickle.loads()` with insecure serialization disabled","details":"vLLM is an inference and serving engine for large language models. 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.","published":"2026-10-26T16:54:00.643Z","modified":"2026-10-28T02:59:28.946833455Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/vllm-project/vllm/commit/3d5625cc3c2474994107047d7a6ecb8e4008f9b0","label":"vllm-project/vllm@3d5625c"},"references":[{"type":"WEB","url":"https://github.com/vllm-project/vllm/releases/tag/v0.32.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115912.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-6757-hggm-hp2w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115912"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/3d5625cc3c2474994107047d7a6ecb8e4008f9b0"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/59357"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:59:28.946833455Z"}}
