Input validation vulnerability in Responsive Tabs For WPBakery Page Builder (formerly Visual Composer) 1.1

The Responsive Tabs For WPBakery Page Builder plugin for WordPress is vulnerable to a security issue known as Stored Cross-Site Scripting. This affects versions up to and including 1.1. This means that, if an attacker has certain permissions, they can add malicious code into pages on a WordPress website. This code will then be executed whenever someone views the page. This is a serious security risk and should be taken seriously.
