CVE-2022-2542

uContext for Clickbank <= 3.9.1 - Cross-Site Request Forgery to Cross-Site Scripting

8.8 High

The uContext for Clickbank plugin for WordPress is vulnerable to Cross-Site Request Forgery to Cross-Site Scripting in versions up to, and including 3.9.1. This is due to missing nonce validation in the ~/app/sites/ajax/actions/keyword_save.php file that is called via the doAjax() function.
