The thumbnail generation system passes filenames wrapped in shell double-quotes directly to exec() without escapeshellarg() sanitization, allowing filenames such as $(PAYLOAD).mp4 to survive the filename sanitizer and be evaluated as shell commands when ffmpeg, ImageMagick, vips, or stl-thumb processes the file during thumbnail generation.","published":"2026-08-11T21:17:25.867","modified":"2026-08-11T21:17:25.867","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://filerun.com/"},{"type":"WEB","url":"https://filerun.com/index.php/changelog?v=2026.2.1"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/filerun-rce-via-thumbnail-generation-command-injection"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T21:17:25.867"}}
