Mercado Pago payments for WooCommerce: Currently marked unpatched

Affected versions: *-8.7.11

Vulnerability type: CWE-862 Missing Authorization

The Mercado Pago payments for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'mp_pix_image' WooCommerce API endpoint in all versions up to, and including, 8.7.11.
