SCA: security update for github.com/filebrowser/filebrowser/v2 (GHSA-9f3r-2vgw-m8xp)

medium Tenable Cloud Security Plugin ID 438875

Description

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

 - File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files
 within a specified directory. Versions 2.61.2 and below are vulnerable to Path Traversal through the
 resourcePatchHandler (http/resource.go). The destination path in resourcePatchHandler is validated against
 access rules before being cleaned/normalized, while the actual file operation calls path.Clean()
 afterward—resolving .. sequences into a different effective path. This allows an authenticated user with
 Create or Rename permissions to bypass administrator-configured deny rules (both prefix-based and regex-
 based) by injecting .. sequences in the destination parameter of a PATCH request. As a result, the user
 can write or move files into any deny-rule-protected path within their scope. However, this cannot be used
 to escape the user's BasePathFs scope or read from restricted paths. This issue has been fixed in version
 2.62.0. (CVE-2026-32758)

Solution

Update the github.com/filebrowser/filebrowser/v2 library and its related packages to version 2.62.0 or later.
