When processing `video/jpeg` data URLs, the method splits the base64 string on commas without enforcing a frame count limit. A single request to the OpenAI-compatible chat completions API containing thousands of frames can exhaust server memory and crash it, and no authentication is required.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-5497","publishedAt":"2026-06-11T10:16:21.903Z","cveId":"CVE-2026-5497","cweIds":["CWE-400"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":["vllm@>= 0.8.0, < 0.19.0 (fixed: 0.19.0)"],"affectedPackageNames":["vllm"],"affectedPackageRefs":["pypi:vllm"],"affectedVendors":[],"affectedVendorsRaw":["vLLM"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"vLLM out-of-memory denial of service via unbounded video frames in data URLs","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00537,"epssCheckedAt":"2026-11-04T00:12:27.710Z","kevDateAdded":null,"advisoryAliases":["GHSA-wcwg-c5fc-9vrc"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:47:42.782Z","patchAvailable":true,"disclosureDate":"2026-06-11T10:16:21.903Z","fixReleasedAt":"2026-04-03T04:04:52.833Z","daysToFix":-69,"fixCheckedAt":"2026-10-29T21:34:42.899Z","capecIds":["CAPEC-125","CAPEC-130"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"vllm","fixedVersion":"0.19.0","matchedVersion":"0.19.0","fixReleasedAt":"2026-04-03T04:04:52.833Z","daysToFix":-69,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:34:42.717Z"}]}}
