The parameter has no maximum length validation and is processed on the single EngineCore scheduler thread. Unauthenticated attackers can send multi-hundred-megabyte salt values that trigger expensive pickle serialization and SHA-256 hashing, stalling the scheduler and denying service to all concurrent requests.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-100647","publishedAt":"2026-09-26T14:16:47.097Z","cveId":"CVE-2026-100647","cweIds":["CWE-20"],"cvssScore":"5.3","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 denial of service through oversized cache_salt parameter","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00348,"epssCheckedAt":"2026-11-12T15:03:08.607Z","kevDateAdded":null,"advisoryAliases":["GHSA-hm89-h84f-px3x"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-08T06:09:33.012Z","patchAvailable":null,"disclosureDate":"2026-09-26T14:16:47.097Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[]}}
