Base vector

AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: The Popups, Welcome Bar, Optins and Lead Generation Plugin WordPress plugin versions prior to 2.0.5

Description: The issue is related to a reflected Cross-Site Scripting problem. It occurs because the message id parameter of the get message action row AJAX action is not properly sanitized and escaped before being outputted back in an attribute. This leads to a security issue where an attacker could potentially inject malicious scripts.

Recommendations: For versions prior to 2.0.5, update to version 2.0.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the get message action row AJAX action to minimize the risk of exploitation. Avoid using the message id parameter in the affected AJAX endpoint until the issue is resolved.
