CVE-2025-15041

Description

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the save_site_option() function in all versions up to, and including, 5.6.2. This makes it possible for authenticated attackers, with level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site.
