An authenticated caller of the /v1/responses endpoint can supply an attacker-controlled template in chat_template_kwargs[chat_template] when no server template is configured, because ChatParams.get_apply_chat_template_kwargs() keeps that value without enforcing trust_request_chat_template. The bypassed trust policy lets the attacker exhaust CPU or memory through Jinja rendering.","solution":"Fixed in 0.32.0.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-115918","publishedAt":"2026-10-26T18:17:39.440Z","cveId":"CVE-2026-115918","cweIds":["CWE-400","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 Jinja chat template injection through /v1/responses endpoint","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,"epssCheckedAt":"2026-10-27T06:10:23.088Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-27T06:10:29.116Z","patchAvailable":null,"disclosureDate":"2026-10-26T18:17:39.440Z","capecIds":["CAPEC-125","CAPEC-130"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
