Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker with a valid account on a WordPress site to change important settings, such as granting themselves administrative access. It occurs because the plugin fails to properly check if the user has permission to make these changes, making it easier for attackers to exploit the flaw.

Technical 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.
