CVE-2022-2556Public exploitNetwork attack vector

Internal-network scanning via caller-controlled AJAX URL

Published Aug 29, 2022 · Updated Aug 3, 2024

Server-side request forgery in Mailchimp for WooCommerce before 2.7.2 allows remote authenticated users to probe internal services. The mailchimp_woocommerce_oauth_status AJAX action accepts a caller-supplied URL, makes a server-side POST request, and appends the response body to its reply. Administrator privileges are required, and the disclosed consequence is internal-network scanning and response-data disclosure rather than data modification or service interruption.
