What is CVE-2025-13997?

The King Addons for Elementor plugin for WordPress allows unauthorized access to sensitive API keys. All versions up to and including 51.1.49 expose critical API keys, such as those for Mailchimp, Facebook, and Google. This occurs because the plugin improperly adds these keys to the HTML source code via the render_full_form function. Attackers can exploit this vulnerability to gain unauthorized access to API secrets, posing a significant threat to website security, particularly for users with a Premium license.
