Advisory

Source description from Wordfence Intelligence, credited to DANIEL CID.

The Gravityforms plugin for WordPress is vulnerable to Cross-Site Scripting in versions up to, and including, 1.9.6 due to insufficient input sanitization and output escaping alongside the use of add_query_arg or remove_query_arg(). This makes it possible for attackers to inject arbitrary web scripts that execute in a victim's browser.
