The vulnerability was publicly disclosed on August 3, 2022, and was discovered by Miguel Xavier Penha Neto (WPScan).

The vulnerability exists in an AJAX action within the plugin that enables authenticated users with high privileges to execute POST requests to internal networks. The vulnerability has been assigned a CVSS score of 2.7 (low severity) and is classified under CWE-918. The exploit involves sending a specially crafted POST request to the wp-admin/admin-ajax.php endpoint, with the response including the body of the request, potentially enabling internal network scanning (WPScan).

When exploited, this vulnerability could allow authenticated administrators to perform server-side requests to internal networks and potentially scan private networks. The response includes the body of the request, which could expose sensitive internal network information (WPScan).

The vulnerability has been patched in version 2.7.2 of the MailChimp for WooCommerce plugin. Users are advised to update to this version or later to mitigate the risk (WPScan).
