{"cve":"CVE-2026-25889","nvd":{"published":"2026-02-09T22:16:03.723","modified":"2026-06-17T10:25:23.157","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 2.57.1, a case-sensitivity flaw in the password validation logic allows any authenticated user to change their password (or an admin to change any user's password) without providing the current password. By using Title Case field name \"Password\" instead of lowercase \"password\" in the API request, the current_password verification is completely bypassed. This enables account takeover if an attacker obtains a valid JWT token through XSS, session hijacking, or other means. This vulnerability is fixed in 2.57.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-178"],"references":["https://github.com/filebrowser/filebrowser/commit/ff2f00498cff151e2fb1f5f0b16963bf33c3d6d4","https://github.com/filebrowser/filebrowser/releases/tag/v2.57.1","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-hxw8-4h9j-hq2r"],"products":["filebrowser:filebrowser"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-25889","score":0.00366,"percentile":0.30508,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hxw8-4h9j-hq2r","url":"https://osv.dev/vulnerability/GHSA-hxw8-4h9j-hq2r","summary":"File Browser has an Authentication Bypass in User Password Update","modified":"2026-02-19T20:41:10.311386Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":["<2.57.1"],"fixed":["2.57.1"]}]},{"id":"GO-2026-4475","url":"https://osv.dev/vulnerability/GO-2026-4475","summary":"File Browser has an Authentication Bypass in User Password Update in github.com/filebrowser/filebrowser","modified":"2026-02-19T20:41:10.311386Z","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":["<2.57.1"],"fixed":["2.57.1"]}]}],"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).
