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.","state":0,"publishedAt":"2026-10-26T16:54:00.643+00:00","modifiedAt":"2026-10-26T16:54:00.643+00:00","affected":[{"ecosystem":"Vendor product","name":"vllm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vllm-project\",\n                    \"product\": \"vllm\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.32.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-6757-hggm-hp2w","https://github.com/vllm-project/vllm/pull/59357","https://github.com/vllm-project/vllm/commit/3d5625cc3c2474994107047d7a6ecb8e4008f9b0","https://github.com/vllm-project/vllm/releases/tag/v0.32.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115912","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115912","identifiers":["CVE-2026-115912"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
