{"cve":"CVE-2026-28492","nvd":{"published":"2026-03-05T21:16:22.630","modified":"2026-06-17T10:28:44.327","status":"Analyzed","description":"File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.61.0, when a user creates a public share link for a directory, the withHashFile middleware in http/public.go uses filepath.Dir(link.Path) to compute the BasePathFs root. This sets the filesystem root to the parent directory instead of the shared directory itself, allowing anyone with the share link to browse and download files from all sibling directories. This issue has been patched in version 2.61.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/filebrowser/filebrowser/commit/31194fb57a5b92e7155219d7ec7273028fcb2e83","https://github.com/filebrowser/filebrowser/releases/tag/v2.61.0","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-mr74-928f-rw69"],"products":["filebrowser:filebrowser"],"source":"nvd","synced_at":"2026-10-19T22:25:53.701907451+00:00"},"epss":{"cve":"CVE-2026-28492","score":0.00374,"percentile":0.31333,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-mr74-928f-rw69","url":"https://osv.dev/vulnerability/GHSA-mr74-928f-rw69","summary":"FileBrowser has Path Traversal in Public Share Links that Exposes Files Outside Shared Directory","modified":"2026-03-23T04:56:00.211469829Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.61.0"],"fixed":["2.61.0"]}]},{"id":"GO-2026-4585","url":"https://osv.dev/vulnerability/GO-2026-4585","summary":"FileBrowser has Path Traversal in Public Share Links that Exposes Files Outside Shared Directory in github.com/filebrowser/filebrowser","modified":"2026-03-23T04:53:11.725060Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","purl":"pkg:golang/github.com/filebrowser/filebrowser","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.61.0"],"fixed":["2.61.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
