What the vulnerability does
The Add User Meta 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 'add-user-meta' page. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Add User Meta versions 1.0.1 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the site without the admin's knowledge or consent. The attack requires the victim to visit the attacker's page while authenticated to the WordPress site.
What an attacker can do
Perform unwanted actions on the site by tricking an authenticated admin into visiting a malicious webpage.
Potential impact on your site
An attacker can modify site settings or data by exploiting an admin's browser session without their awareness.
Conditions required to exploit
Site admin must be logged in and visit an attacker-controlled webpage; no special privileges required.
