What is CVE-2025-10579?
CVE-2025-10579 is a medium-severity missing authorization vulnerability in wp_media BackWPup – WordPress Backup & Restore Plugin, published on 25 Oct 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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).
