Summary

The Mailgun for WordPress plugin before version 2.2.1 does not perform any capability or nonce check on an unauthenticated AJAX action that adds subscribers to the site owner's configured email service mailing lists. This allows unauthenticated attackers to enrol arbitrary email addresses into those lists using the owner's stored API credentials.

Risk Assessment

An attacker can abuse sending limits or domain reputation by enrolling unwanted email addresses, potentially leading to account suspension or costs.

Recommendation

Update the Mailgun plugin to version 2.2.1 or later.
