{"cve":"CVE-2026-27611","nvd":{"published":"2026-02-25T03:16:05.463","modified":"2026-06-17T10:27:23.553","status":"Analyzed","description":"FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to versions 1.1.3-stable and 1.2.6-beta, when users share password-protected files, the recipient can completely bypass the password and still download the file. This happens because the API returns a direct download link in the details of the share, which is accessible to anyone with JUST THE SHARE LINK, even without the password. Versions 1.1.3-stable and 1.2.6-beta fix the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:L/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:N/UI:R/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200","CWE-287","CWE-288"],"references":["https://github.com/gtsteffaniak/filebrowser/commit/c51b0ee9738fa4599b409f47c5bf820ef31b4fe1","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-8vrh-3pm2-v4v6","https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-8vrh-3pm2-v4v6"],"products":["gtsteffaniak:filebrowser_quantum"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27611","score":0.00366,"percentile":0.30461,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8vrh-3pm2-v4v6","url":"https://osv.dev/vulnerability/GHSA-8vrh-3pm2-v4v6","summary":"FileBrowser Quantum: Password Protection Not Enforced on Shared File Links ","modified":"2026-05-05T15:55:59.579703Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser/backend","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser/backend","ranges":["<0.0.0-20260221163904-dbcfba993b85"],"fixed":["0.0.0-20260221163904-dbcfba993b85"]}]},{"id":"GO-2026-4546","url":"https://osv.dev/vulnerability/GO-2026-4546","summary":"FileBrowser Quantum: Password Protection Not Enforced on Shared File Links in github.com/gtsteffaniak/filebrowser/backend","modified":"2026-02-25T23:41:19.078880Z","packages":[{"ecosystem":"Go","name":"github.com/gtsteffaniak/filebrowser/backend","purl":"pkg:golang/github.com/gtsteffaniak/filebrowser/backend","ranges":["<0.0.0-20260221163904-dbcfba993b85"],"fixed":["0.0.0-20260221163904-dbcfba993b85"]}]}],"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).
