We have noticed the Builder Contact addon had security vulnerability allowing hackers to send spam/phishing emails on behalf of the affected sites. The issue was first reported by a few of our members on the support forum and at the same time we were notified by the WordFence team (big thanks to WordFence team for notifying us the concerns and suggestions). We took immediate action to fix all security flaws and released the update. If you are using Builder Contact prior version 1.4.6, it is highly recommended to update to the latest version immediately. If you have the old Builder Contact version installed on the server but not activated, please either delete it or replace it with the latest version (do not leave the compromised version on the server). If your membership has expired and can't update Builder Contact, please contact us. We will offer a 3-month free membership extension so you can update the plugin. We apologize for any inconvenience it may cause.
