How to fix?

Upgrade thorsten/phpmyfaq to version 3.2.6 or higher.

Overview

thorsten/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases

Affected versions of this package are vulnerable to Arbitrary File Upload via the manipulation of the Content-type and lang parameters in the category image upload function. An attacker can upload malicious files with a .php extension, potentially leading to unauthorized system access and control by modifying the Content-type to return an empty string for the extension and setting the lang parameter to .php., thereby enabling the uploading of web shells.
