Attackers can replay a valid multimodal item with repeated or overlapping mm_placeholders ranges or mismatched kwargs_data and mm_hashes lists, producing a negative text span in Qwen2.5-VL position construction that terminates the engine.","state":0,"publishedAt":"2026-10-25T13:20:17.838+00:00","modifiedAt":"2026-10-25T13:20:17.838+00:00","affected":[{"ecosystem":"Vendor product","name":"vllm","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vllm-project\",\n                    \"product\": \"vllm\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:pypi/vllm\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0.20.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"0.30.0\"\n                        },\n                        {\n                            \"version\": \"0.30.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-34qw-q2h2-jp3m","https://www.vulncheck.com/advisories/vllm-0.20.0-before-0.30.0-dos-via-inference-v1-generate-mm-placeholders"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116178","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116178","identifiers":["CVE-2026-116178"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
