Jeg fikk info rett fra utviklerne, fikk også info fra Envato en stund etterpå.
We are getting in touch to let you know about multiple XSS security vulnerabilities in the
Visual Composer WordPress plugin versions prior to 4.7.4 (releases prior to October 2, 2015).
We have been working with WP Bakery, the creators of Visual Composer, who have addressed all identified vulnerabilities in version 4.7.4 and later, and undertaken a code audit to ensure that it is as secure as possible.
What You Should Do
In order to secure your item(s) from these vulnerabilities we strongly encourage you to update to version 4.7.4 or later as soon as possible. Instructions on how to update Visual Composer can be found on the
WPBakery website.
You can check whether you have updated successfully by going to the WordPress dashboard Plugins page and checking the Visual Composer entry.
Please make sure that the version number says 4.7.4.
If you have used this plugin in projects for clients, please help them to secure their sites as well.
Your Security is Our Priority
We take security seriously at Envato. When we receive security vulnerability reports for items sold on our marketplaces, we work as quickly as possible to validate the report, investigate risk and determine the best course of action for the security of our community.
On behalf of the plugin creator and Envato, we'd like to apologise for this inconvenience and assure you that your security always is and will be our priority.
Regards,
The Envato Team
