email from Sucuri Security to The Image Stop ltd.

During a routine audit of our Web Application Firewall (WAF), we discovered a stored XSS vulnerability affecting the Jetpack WordPress Plugin, one of the most popular plugins of the WordPress ecosystem.

Security Risk: Dangerous

This email does not mean you are affected!! Being proactive in the protection of your site is one of the most important aspects of having a solid security posture. Therefore, we feel it’s important to research and report on all potential threats as quickly as possible.

The vulnerability affects users of Jetpack versions < = to 3.7 that use the contact form module present in the plugin, which is activated by default. An attacker can exploit this issue by providing a specially crafted malicious email address in one of the site’s contact form pages.
