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.","publishedAt":"2026-02-25T02:24:48.357Z","updatedAt":"2026-02-27T17:11:18.122Z","severity":{"score":7.1,"label":"High","version":"4.0","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","source":"GitHub_M"},"assigner":"GitHub_M","products":["gtsteffaniak filebrowser"],"affected":[{"vendor":"gtsteffaniak","product":"filebrowser","versions":[{"version":"< 1.1.3-stable","status":"affected"},{"version":">= 1.2.0-beta, < 1.2.6-beta","status":"affected"}]}],"references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-8vrh-3pm2-v4v6","https://github.com/gtsteffaniak/filebrowser/commit/c51b0ee9738fa4599b409f47c5bf820ef31b4fe1"],"weaknesses":["CWE-200","CWE-288","CWE-287"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/27xxx/CVE-2026-27611.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-27611","state":"PUBLISHED","datePublished":"2026-02-25T02:24:48.357Z","dateUpdated":"2026-02-27T17:11:18.122Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-20T19:43:14.602Z"},"containers":{"cna":{"title":"FileBrowser Quantum: Password Protection Not Enforced on Shared File Links","descriptions":[{"lang":"en","value":"FileBrowser Quantum is a free, self-hosted, web-based file manager.
