Name of the Vulnerable Software and Affected Versions The Popup by Supsystic WordPress plugin versions prior to 1.10.5

Description The issue is related to a reflected Cross-Site Scripting problem. It occurs because the tab parameter of the plugin's options page is not properly sanitized before being output in an attribute. This allows for malicious scripts to be injected.

Recommendations For versions prior to 1.10.5, update to version 1.10.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the plugin's options page to minimize the risk of exploitation.
