Name of the Vulnerable Software and Affected Versions Link Library WordPress plugin versions prior to 7.2.9

Description The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the settingscopy parameter is not properly sanitised and escaped before being outputted back in an admin page.

Recommendations For versions prior to 7.2.9, update to version 7.2.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin page where the settingscopy parameter is outputted to minimize the risk of exploitation. Avoid using the settingscopy parameter in the affected admin page until the issue is resolved.
