Prior to 2.63.17, File Browser builds new user scopes from usernames passed through cleanUsername() when Signup=true and CreateUserDir=true, but the many-to-one normalization can collapse usernames such as team/one, team one, and team-one to the same home directory without checking whether the resulting scope is already taken, allowing a second registrant to gain full read and write access to another user's files. This issue is fixed in version 2.63.17.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1},"cwes":["CWE-647","CWE-706"],"references":["https://github.com/filebrowser/filebrowser/commit/883a36f02fcb69566a8628cb47f18fdc73348387","https://github.com/filebrowser/filebrowser/releases/tag/v2.63.17","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-7rc3-g7h6-22m7","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-7rc3-g7h6-22m7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-62685","score":0.00553,"percentile":0.46191,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7rc3-g7h6-22m7","url":"https://osv.dev/vulnerability/GHSA-7rc3-g7h6-22m7","summary":"File Browser: Colliding username normalization gives two users the same home directory","modified":"2026-07-22T21:11:40.261802198Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.63.17"],"fixed":["2.63.17"]}]},{"id":"GO-2026-6024","url":"https://osv.dev/vulnerability/GO-2026-6024","summary":"File Browser: Colliding username normalization gives two users the same home directory in github.com/filebrowser/filebrowser","modified":"2026-07-22T21:00:24.278887693Z","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":["<2.63.17"],"fixed":["2.63.17"]}]}],"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).
