CVE-2023-6591

Name of the Vulnerable Software and Affected Versions Popup Box WordPress plugin versions prior to 20.9.0

Description The issue allows high privilege users, such as admins, to perform Cross-Site Scripting attacks even when unfiltered html is disallowed, due to the plugin not sanitizing and escaping some of its settings.

Recommendations For versions prior to 20.9.0, update to version 20.9.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's settings to minimize the risk of exploitation.
