{"id":"CVE-2026-115915","aliases":["GHSA-h3rc-j82p-2c3h"],"url":"https://o3.security/vulnerability/CVE-2026-115915","summary":"vLLM: Untrusted EPS inputs can trigger denial of service or Ghostscript RCE","details":"vLLM is an inference and serving engine for large language models. Prior to 0.32.0, ImageMediaIO passes attacker-controlled image bytes to Pillow through Image.open(BytesIO(data)) without restricting decoder selection, and the MIME label does not constrain the selected format. Image-capable request paths through parse_image() and fetch_image() can therefore dispatch an EPS payload to host components. A host with Ghostscript affected by CVE-2024-29510 can execute commands with the vLLM process's privileges, while environments using Pillow 12.0.0 through 12.2.0 can trigger CVE-2026-59203 and exhaust media-loading workers. Deployments without the applicable vulnerable dependency are not affected by that corresponding impact. This issue is fixed in version 0.32.0.","published":"2026-10-26T17:16:06.387Z","modified":"2026-10-28T02:59:28.909828575Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/vllm-project/vllm/commit/710ac56e691d4713feca50a43e6c440f07d373fd","label":"vllm-project/vllm@710ac56"},"references":[{"type":"WEB","url":"https://github.com/vllm-project/vllm/releases/tag/v0.32.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/115xxx/CVE-2026-115915.json"},{"type":"ADVISORY","url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-h3rc-j82p-2c3h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-115915"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/commit/710ac56e691d4713feca50a43e6c440f07d373fd"},{"type":"FIX","url":"https://github.com/vllm-project/vllm/pull/60022"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:59:28.909828575Z"}}
