What is CVE-2020-37244?

The Supsystic Membership plugin version 1.4.7 is vulnerable to SQL injection, allowing unauthenticated attackers to execute arbitrary SQL commands.

This flaw poses significant risks, making it essential for users to update their plugins and secure their WordPress installations.
