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.","categories":["Unclassified"],"product":"vllm","vendor":"vllm-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116178","source_modified_at":"2026-10-25T13:20:17.838Z","fetched_at":"2026-10-25T16:01:37.004770Z","product":"vllm","vendor":"vllm-project","versions":[{"version":"0.20.0","status":"affected","versionType":"semver","lessThan":"0.30.0"},{"version":"0.30.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116178","source_modified_at":"2026-10-25T13:20:17.838Z","fetched_at":"2026-10-25T16:01:37.004770Z","package":{"name":"vllm","ecosystem":null},"version":"0.30.0","basis":"first unaffected version stated in the CVE record"}],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-25T13:20:17.838Z","modified_at":"2026-10-25T13:20:17.838Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116178","fetched_at":"2026-10-25T16:01:37.004770Z","source_modified_at":"2026-10-25T13:20:17.838Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-34qw-q2h2-jp3m","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/vllm-0.20.0-before-0.30.0-dos-via-inference-v1-generate-mm-placeholders","tags":["third-party-advisory"]}],"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":"2026-10-25T13:20:17.838Z","content_hash":"75b50bbd90cd0d4c456e68fb71b5a60305afb95c37668edef48a399c7bf83f1e"}}
