Name of the Vulnerable Software and Affected Versions MonsterInsights WordPress plugin versions prior to 11.1.0
Description An issue exists where the software fails to correctly validate the signature on an unauthenticated AJAX action. When the plugin is not connected to Google Analytics, the HMAC (Hash-based Message Authentication Code) signing key remains empty. This allows unauthenticated attackers to forge a valid signature and overwrite a configuration value, which disrupts server-side analytics when operating in Manual GA4 mode.
Recommendations Update MonsterInsights WordPress plugin to version 11.1.0 or later.
