 "title": "Another Mailchimp Widget <= 2.1.0 - Improper Certificate Validation in Mailchimp API Requests",
 "description": "The Another Mailchimp Widget plugin for WordPress is vulnerable to improper certificate validation in all versions up to, and including, 2.1.0 due to TLS certificate verification being disabled ('sslverify' => false) for Mailchimp API requests that carry the API key in an HTTP Basic authorization header. This makes it possible for unauthenticated attackers in a man-in-the-middle network position to intercept these requests and steal the site's Mailchimp API key.",
