Description

The Royal Elementor Addons plugin for WordPress is vulnerable to unauthenticated API key disclosure in versions up to, and including, 1.3.70 due to the plugin adding the API key to the source code of any page running the MailChimp block.

We recommend resetting any MailChimp API keys if running a vulnerable version of this plugin with the MailChimp block enabled as the API key may have been compromised.
