This article explains how you can identify if your Cloud Security Plus installation is affected, and fix it. It also offers the steps to protect your installation even if it is not affected.
What is the issue?
Cloud Security Plus had a vulnerable endpoint (CVE-2020-24786) that allowed users to integrate their installation with other ManageEngine product installations, bypassing authentication. This could potentially lead to a data leak.

2. Verify that the Email Server settings (Admin > Email settings) are the same and have not been changed.
3. In Domain Settings, check if new, additional, or illegitimate domains have been configured.
