Technical ContextAI · show details
This vulnerability (CWE-284: Improper Access Control) affects Simple User Registration (WordPress plugin). The Simple User Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 6.7 due to insufficient restriction on the 'profile_save_field' 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.

DescriptionCVE.org
The Simple User Registration plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 6.7 due to insufficient restriction on the 'profile_save_field' 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.
Executive ViewAI
The Simple User Registration WordPress plugin (versions ≤6.7) contains a critical access control flaw that could allow unauthorized users to bypass authentication and access sensitive functionality. Organizations using this plugin face immediate risk of unauthorized account creation, data exposure, or system compromise until remediation is completed.
Disable the Simple User Registration plugin immediately if not essential to operations. If required, implement WAF rules to restrict registration endpoints to authorized IP ranges, enforce WordPress authentication at the web server level, disable user self-registration via WordPress settings, implement network segmentation to limit plugin exposure, and enable comprehensive logging of registration activities for detection of exploitation attempts.
