The vulnerability was discovered and disclosed on December 19, 2024, and was assigned CVE-2024-12736. The issue affects the plugin's admin interface and could potentially be exploited against high-privilege users such as administrators (WPScan).

Currently, there is no known fix available for this vulnerability. Site administrators running affected versions should consider either removing the plugin or implementing additional security controls to restrict access to the admin interface (WPScan).
