SCA: security update for github.com/filebrowser/filebrowser/v2 (GHSA-mr74-928f-rw69)

high Tenable Self-Hosted Container Security Plugin ID 438394

Description

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

 - 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 version 2.61.0, when a user creates a public share link
 for a directory, the withHashFile middleware in http/public.go uses filepath.Dir(link.Path) to compute the
 BasePathFs root. This sets the filesystem root to the parent directory instead of the shared directory
 itself, allowing anyone with the share link to browse and download files from all sibling directories.
 This issue has been patched in version 2.61.0. (CVE-2026-28492)
