Upgrade phpmyfaq/phpmyfaq to version 4.1.9, 4.2.0-beta or higher.
Overview
phpmyfaq/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases
Affected versions of this package are vulnerable to Missing Authorization via the attachment download endpoint (attachment.php) due to a flawed permission check. The condition ($groupPermission || $groupPermission && $userPermission) evaluates to true whenever $groupPermission is truthy, making the $userPermission check irrelevant and allowing any authenticated user to download attachments they are not authorized to access. An attacker with a valid session can retrieve restricted FAQ attachments by requesting the endpoint with a known attachment ID.
Note: This is only exploitable when the records.allowDownloadsForGuests flag is enabled, or when the installation has users who hold the dlattachment permission - conditions common in deployments that actively use attachments.
