CVE-2024-9195: Whmpress Whmcs Client Area

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The WHMPress - WHMCS Client Area plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the update_settings case in the /admin/ajax.php file in all versions up to, and including, 4.3-revision-3. This makes it possible for authenticated attackers, with Subscriber-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.

Affected products

• Whmpress Whmcs Client Area: before 4.3 (fixed in 4.3); version 4.3 only
