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.","published_at":"2026-06-11T08:31:18.953000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-400"],"nvd_references":["https://huntr.com/bounties/7bd92629-b396-4449-8f88-6c0092530eb4","https://github.com/vllm-project/vllm/commit/58ee61422169ce17e08248f8efa1e9df434fe395"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:55.040689Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"vllm-project","vendor_name":"vllm-project","product_slug":"vllm-project-vllm","product_name":"vllm-project/vllm","version_start":"unspecified","version_start_inclusive":true,"version_end":"0.19.0","version_end_inclusive":false,"cpe23_uri":"cve5:vllm-project:vllm-project-vllm:unspecified:0.19.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/7bd92629-b396-4449-8f88-6c0092530eb4","source_type":"MISC","tags":[]},{"url":"https://github.com/vllm-project/vllm/commit/58ee61422169ce17e08248f8efa1e9df434fe395","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-11T08:31:18.953000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:48.239489Z","label":"CVSS score revised","source":"cvelistv5"}]}
