What is CVE-2026-23693?

The ElementsKit Lite WordPress plugin versions prior to 3.7.9 have a significant issue that exposes the REST endpoint /wp-json/elementskit/v1/widget/mailchimp/subscribe without requiring authentication. This vulnerability allows unauthenticated users to supply their own Mailchimp API credentials and bypass security measures, leading to insufficient validation of parameters. As a result, an attacker could exploit this endpoint to manipulate Mailchimp subscription data, disrupt API functionality, and impact server resources on the vulnerable WordPress site.
