Add User Meta WordPress Plugin Cross-Site Request Forgery Vulnerability

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the Add User Meta plugin for WordPress, affecting all versions through 1.0.1. The vulnerability arises from inadequate nonce validation on the 'add-user-meta' page, allowing unauthenticated attackers to manipulate settings and inject malicious scripts. Exploitation requires tricking a site administrator into clicking a link that initiates the forged request.

Impact

Exploitation of this vulnerability could lead to Cross-Site Scripting (XSS) attacks, where injected scripts are executed in the context of the user.
