The vulnerability exists due to improper sanitization and escaping of the 'old_domain' parameter in the plugin.

The vulnerability has been assigned a CVSS score of 7.5 (high) and is classified under CWE-79 (WPScan).

This vulnerability could be exploited against high-privilege users such as administrators. When successfully exploited, it allows attackers to execute malicious scripts in the context of the victim's browser session (WPScan).

The vulnerability can be exploited through a POST request to the affected endpoint. A proof of concept exists that demonstrates the exploitation by logging in as an admin and triggering the XSS through a specially crafted request (WPScan).

At the time of disclosure, there was no known fix available for this vulnerability. Users of the affected plugin should consider implementing additional security controls or removing the plugin until a patch is available (WPScan).
