When processing `video/jpeg` data URLs, the method splits the base64 data string on commas to extract individual JPEG frames without enforcing a frame count limit. An attacker can exploit this by crafting a single API request containing thousands of comma-separated base64-encoded JPEG frames in a data URL, causing the server to decode all frames into memory and crash due to excessive memory consumption. This vulnerability is reachable via the OpenAI-compatible chat completions API and does not require authentication."}],"affected":[{"vendor":"vllm-project","product":"vllm-project/vllm","versions":[{"version":"unspecified","lessThan":"0.19.0","status":"affected","versionType":"custom"}]}],"references":[{"url":"https://huntr.com/bounties/7bd92629-b396-4449-8f88-6c0092530eb4"},{"url":"https://github.com/vllm-project/vllm/commit/58ee61422169ce17e08248f8efa1e9df434fe395"}],"metrics":[{"cvssV3_0":{"version":"3.0","attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","confidentialityImpact":"NONE","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-400 Uncontrolled Resource Consumption","cweId":"CWE-400"}]}],"source":{"advisory":"7bd92629-b396-4449-8f88-6c0092530eb4","discovery":"EXTERNAL"}},"adp":[{"references":[{"url":"https://huntr.com/bounties/7bd92629-b396-4449-8f88-6c0092530eb4","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-11T14:01:03.081885Z","id":"CVE-2026-5497","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-11T14:01:07.379Z"}}]}}
