Inference clients can bypass the server frame limit by setting media_io_kwargs.video.num_frames in chat completion requests. Setting num_frames to -1, or to a large value with many base64 JPEG frames, forces VideoMediaIO to decode all frames and np.stack them, exhausting memory.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-126399","publishedAt":"2026-11-13T10:17:44.260Z","cveId":"CVE-2026-126399","cweIds":["CWE-770"],"cvssScore":"6.5","cvssSeverity":"medium","severity":"medium","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["vLLM"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"vLLM resource exhaustion via video frame limit bypass in chat completions","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00476,"epssCheckedAt":"2026-11-13T18:11:31.384Z","kevDateAdded":null,"advisoryAliases":["GHSA-gm8j-8578-p8q4"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-13T18:11:34.299Z","patchAvailable":null,"disclosureDate":"2026-11-13T10:17:44.260Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-130"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[]}}
