Announcement & Notification Banner – Bulletin

Multiple plugins and/or themes for WordPress are vulnerable to Reflected Cross-Site Scripting via the url parameter in various versions due to insufficient input sanitization and output escaping. 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.
