critical Tenable Self-Hosted Container Security Plugin ID 441430

Description

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

- FileBrowser Quantum is a free, self-hosted, web-based file manager. Prior to 1.3.1-stable and 1.3.9-beta,
attacker-controlled path input is joined with a trusted base path prior to sanitization, allowing
traversal sequences (e.g., ../) to escape the intended shared directory. As a result, an unauthenticated
attacker possessing a valid public share hash with delete permissions enabled can delete arbitrary files
outside the shared directory within the share owner’s configured storage scope. This affects
public/api/resources and public/api/resources/bulk. This vulnerability is fixed in 1.3.1-stable and
1.3.9-beta. (CVE-2026-44542)

Solution

Update the github.com/gtsteffaniak/filebrowser library and its related packages to version 0.0.0-20260501183844-112740bdd41d or later.
