critical Tenable Cloud Security Plugin ID 439525

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. Prior to version 2.62.2, the signupHandler in File Browser applies default
user permissions via d.settings.Defaults.Apply(user), then strips only Admin. The Execute permission and
Commands list from the default user template are not stripped. When an administrator has enabled signup,
server-side execution, and set Execute=true in the default user template, any unauthenticated user who
self-registers inherits shell execution capabilities and can run arbitrary commands on the server. This
issue has been patched in version 2.62.2. (CVE-2026-34528)

Solution

Update the github.com/filebrowser/filebrowser/v2 library and its related packages to version 2.62.2 or later.
