Name of the Vulnerable Software and Affected Versions Email Subscription Popup plugin for WordPress versions up to, and including, 1.2.18

Description The issue is related to Reflected Cross-Site Scripting via the HTTP REFERER header due to insufficient input sanitization and output escaping. This allows 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.

Recommendations For versions up to, and including, 1.2.18, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the plugin's functionality to minimize the risk of exploitation.
