Description
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.

Executive Summary

This vulnerability exists in the Simple User Registration plugin for WordPress (up to version 6.7) where the 'profile_save_field' function does not properly restrict access. As a result, an authenticated user with minimal permissions (such as a subscriber) can escalate their privileges by modifying their user role through the 'wp_capabilities' parameter during a profile update.

Impact Analysis

An attacker with minimal permissions can exploit this vulnerability to escalate their privileges, potentially gaining administrative or higher-level access. This can lead to unauthorized control over the WordPress site, including the ability to modify content, manage users, and compromise the site's integrity, confidentiality, and availability.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Simple User Registration plugin for WordPress to a version later than 6.7 where the issue is fixed. Additionally, restrict user permissions to prevent subscribers or low-privileged users from modifying the 'wp_capabilities' parameter during profile updates until the patch is applied.
