Placeholder tokens such as <|audio_|> and <|image_|> are replaced through inefficient list concatenation, giving the algorithm quadratic time complexity (O(n²)). A malicious actor can send specially crafted inputs to trigger resource exhaustion.","solution":"Fixed in 0.8.5.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-46560","publishedAt":"2025-04-30T05:15:52.097Z","cveId":"CVE-2025-46560","cweIds":["CWE-1333"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["vllm@>= 0.8.0, < 0.8.5 (fixed: 0.8.5)"],"affectedPackageNames":["vllm"],"affectedPackageRefs":["pypi:vllm"],"affectedVendors":[],"affectedVendorsRaw":["vLLM"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"vLLM multimodal tokenizer quadratic time complexity resource exhaustion","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00533,"epssCheckedAt":"2026-11-04T06:10:14.827Z","kevDateAdded":null,"advisoryAliases":["GHSA-vc6m-hm49-g9qg"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:53:53.430Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2025-04-28T23:59:40.401Z","daysToFix":-2,"fixCheckedAt":"2026-10-29T21:44:35.323Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"vllm","fixedVersion":"0.8.5","matchedVersion":"0.8.5","fixReleasedAt":"2025-04-28T23:59:40.401Z","daysToFix":-2,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:44:35.171Z"}]}}
