CVE-2023-6009: Userproplugin Userpro

High severity, CVSS 8.8. EPSS: 0.9% chance of exploitation in the next 30 days.

The UserPro plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.1.4 due to insufficient restriction on the 'userpro_update_user_profile' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wp_capabilities' parameter during a profile update.

Affected products

• Userproplugin Userpro: up to and including 5.1.4
