Vulnerability Overview

The Userback plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.13. This is due to missing nonce validation on the userback_save() function. This makes it possible for unauthenticated attackers to update userback user settings via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 1.0.14, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
