MEDIUM

Mailchimp List Subscribe Form <2.0.0 - CSRF

Title source: llm

Description

The Mailchimp List Subscribe Form plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.0.

This makes it possible for unauthenticated attackers to change Mailchimp lists via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
