CVE-2025-10579: Wp Media Backwpup – WordPress Backup & Restore Plugin

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'backwpup_working' AJAX action in all versions up to, and including, 5.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve access to a back-up's filename while a backup is running. This information has little value on it's own, but could be used to aid in a brute force attack to retrieve back-up contents in limited environments (i.e. NGINX).

Affected products

• Wp Media Backwpup – WordPress Backup & Restore Plugin: up to and including 5.5.0
