NVD Description
Note: Versions mentioned in the description apply only to the upstream filebrowser package and not the filebrowser package as distributed by Chainguard.
See How to fix? for Chainguard relevant fixed versions and status.
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.
