Description

The Popup Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via popups in versions up to 4.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
