Executive Summary

The Forminator Forms WordPress plugin before version 1.57.1 has a vulnerability where it does not check if site registration is enabled on a WordPress multisite network before allowing unauthenticated users to create a new site. This can let attackers create a new site and gain administrator privileges on it.

Detection Guidance

Check if your WordPress multisite network allows site registration by inspecting the network settings in the WordPress admin panel. Look for unauthenticated site creation attempts in server logs or WordPress activity logs.

Impact Analysis

If you use a WordPress multisite network with the vulnerable plugin, an unauthenticated attacker could create a new site and take control of it as an administrator. This could lead to unauthorized access, data manipulation, or further attacks on your network.

Compliance Impact

This vulnerability could lead to unauthorized site creation and admin access, potentially violating data protection requirements under GDPR or HIPAA by allowing unauthorized changes to systems handling sensitive data.

Mitigation Strategies

Update the Forminator Forms plugin to version 1.57.1 or later. Disable site registration on your WordPress multisite network if not needed. Restrict unauthenticated access to site creation features.
