Description

Several Smash Balloon Plugins for WordPress are vulnerable to Reflected Cross-Site Scripting via URLs in various versions due to insufficient input sanitization and output escaping with the use of add_query_arg. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
