Attackers can submit concurrent constrained generate requests, including via unauthenticated /invocations, so recycled batch slots apply their token allowlist to victims' unrestricted requests.","categories":["Unclassified"],"product":"vllm","vendor":"vllm-project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114049","source_modified_at":"2026-10-21T00:36:26.938Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"vllm","vendor":"vllm-project","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"0.31.0"},{"version":"0.31.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114049","source_modified_at":"2026-10-21T00:36:26.938Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"vllm","ecosystem":null},"version":"0.31.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00265,"percentile":0.1746,"score_date":"2026-10-23"},"published_at":"2026-10-21T00:36:26.938Z","modified_at":"2026-10-21T00:36:26.938Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114049","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T00:36:26.938Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114049","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-6cxc-2vcg-w5qc","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/vllm-before-0.31.0-stale-allowed-token-ids-mask-via-inputbatch-condense","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":"2026-10-21T00:36:26.938Z","content_hash":"31f2aed98f3734f2bcc7c4a7fff14e0343052fb7facda9d2d4d50f82b745f28e"}}
