Input validation vulnerability in Gravityforms 1.9.6

The Gravityforms plugin for WordPress can be vulnerable to Cross-Site Scripting in versions up to 1.9.6. This happens because the plugin does not properly sanitize and escape user input, and also makes use of add_query_arg or remove_query_arg(). This makes it possible for attackers to insert malicious scripts into a website, which can then be executed by a victim’s browser.
