WordPress Newsletter Plugin 3.2.6 (alert) Reflected XSS Vulnerability

The plugin suffers from a XSS issue due to a failure to properly sanitize user-supplied input to the ‘alert’ GET parameter in the ‘page.php’ script. Attackers can exploit this weakness to execute arbitrary HTML and script code in a user’s browser session.
