Vulnerability CVE-2023-1874
Published: 2023-04-12

Description:
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.

Type:

CWE-266

 (Incorrect Privilege Assignment)
