SCA: security update for github.com/filebrowser/filebrowser/v2 (GHSA-4mh3-h929-w968)

high Tenable Self-Hosted Container Security Plugin ID 437649

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 2.57.1, an authenticated user can bypass the
 application's "Disallow" file path rules by modifying the request URL. By adding multiple slashes (e.g.,
 //private/) to the path, the authorization check fails to match the rule, while the underlying filesystem
 resolves the path correctly, granting unauthorized access to restricted files. This vulnerability is fixed
 in 2.57.1. (CVE-2026-25890)
