From 0.8.3 to before 0.14.1, when an invalid image is sent to vLLM's multimodal endpoint, PIL throws an error. vLLM returns this error to the client, leaking a heap address. With this leak, we reduce ASLR from 4 billion guesses to ~8 guesses. This vulnerability can be chained a heap overflow with JPEG2000 decoder in OpenCV/FFmpeg to achieve remote code execution. This vulnerability is fixed in 0.14.1.","published":"2026-02-02T23:16:07.000Z","lastModified":"2026-07-15T02:18:36.000Z","status":"Modified","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-532","CWE-209"],"affected":["vllm/vllm"],"epss":{"score":0.18542,"percentile":0.97232,"date":"2026-10-26","history":[{"date":"2026-09-27","score":0.10461,"percentile":0.95598},{"date":"2026-10-12","score":0.16697,"percentile":0.96966},{"date":"2026-10-25","score":0.18542,"percentile":0.97232}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 18.5%, higher than 97% of all known CVEs.
