WordPress · Popup Box Wordpress Plugin · CVE-2023-4390
**Name of the Vulnerable Software and Affected Versions**
Popup box WordPress plugin versions prior to 3.7.2
**Description**
The issue allows high-privilege users, such as administrators, to inject arbitrary web scripts, even when the unfiltered html capability is disallowed, for example, in a multisite setup. This is due to the plugin not sanitizing and escaping some Popup fields.
**Recommendations**
For versions prior to 3.7.2, update to version 3.7.2 or later to resolve the issue.
