Name of the Vulnerable Software and Affected Versions BackWPup – WordPress Backup & Restore Plugin versions prior to 5.5.1

Description The BackWPup – WordPress Backup & Restore Plugin for WordPress is susceptible to unauthorized data access. A missing capability check on the backwpup working AJAX action allows authenticated attackers with Subscriber-level access or higher to retrieve a backup’s filename during a backup process. While this information has limited standalone value, it could potentially assist in a brute force attack to obtain backup contents in specific environments, such as those using NGINX. The API endpoint involved is backwpup working.

Recommendations Update BackWPup – WordPress Backup & Restore Plugin to version 5.5.1 or later.
