Summary
The Restrict User Registration plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.0.1. This is due to missing or incorrect nonce validation on the update() function, allowing unauthenticated attackers to update plugin settings via a forged request if they can trick an administrator into performing an action.
Risk Assessment
An attacker could modify plugin settings, potentially leading to violations of user registration policies, such as allowing unauthorized registrations or blocking legitimate ones. This could impact service integrity and availability.
Recommendation
Update the plugin to the latest patched version. Also, implement nonce validation in all functions handling requests.
