{"id":"CVE-2026-54094","aliases":["GHSA-239w-m3h6-ch8v","GO-2026-5055"],"url":"https://o3.security/vulnerability/CVE-2026-54094","summary":"File Browser: Symlink following lets scoped users read, overwrite, and share files outside their filebrowser scope","details":"File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.14, it does not stop the HTTP file handlers from following symbolic links before they open, serve, write, share, or list a file. As a result, a scoped user — and in some cases an unauthenticated public-share recipient — can cross the intended scope boundary by following a symlink whose path is lexically inside their scope but whose target is outside it. This vulnerability is fixed in 2.63.14.","published":"2026-06-25T17:37:14.979Z","modified":"2026-08-12T03:51:21.025553183Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.0047,"percentile":0.3824,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","fixedVersion":"2.63.14"},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54094.json"},{"type":"ADVISORY","url":"https://github.com/filebrowser/filebrowser/security/advisories/GHSA-239w-m3h6-ch8v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54094"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:21.025553183Z"}}
