SCA: security update for github.com/gtsteffaniak/filebrowser/backend (GHSA-8vrh-3pm2-v4v6)

high Tenable Self-Hosted Container Security Plugin ID 438050

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27611)

Solution

Update the github.com/gtsteffaniak/filebrowser/backend library and its related packages to version 0.0.0-20260221163904-dbcfba993b85 or later.
