CVE-2023-1874: Wpdataaccess Wp Data Access

High severity, CVSS 8.8. EPSS: 2.7% chance of exploitation in the next 30 days.

The WP Data Access plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.3.7. This is due to a lack of authorization checks on the multiple_roles_update function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wpda_role[]' parameter during a profile update. This requires the 'Enable role management' setting to be enabled for the site.
