Name of the Vulnerable Software and Affected Versions uContext for Clickbank plugin for WordPress versions up to, and including 3.9.1

Description The issue is due to missing nonce validation in the ~/app/sites/ajax/actions/keyword save.php file, which is called via the doAjax() function. This allows unauthenticated attackers to modify the plugin's settings and inject malicious web scripts via a forged request, provided they can trick a site administrator into performing an action such as clicking on a link.

Recommendations For versions up to, and including 3.9.1, update to a version that includes nonce validation to prevent Cross-Site Request Forgery to Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the ~/app/sites/ajax/actions/keyword save.php file to minimize the risk of exploitation.
