Executive Summary

This is a stored Cross-Site Scripting (XSS) vulnerability in the RegistrationMagic WordPress plugin affecting versions before 6.0.9.9. It allows unauthenticated attackers to inject malicious scripts via a registration form field that is not properly escaped before being displayed in an HTML attribute on an admin page.

Detection Guidance

Check if the RegistrationMagic plugin version is below 6.0.9.9. Look for suspicious form fields in published registration forms that are configured to display on registrant profile pages. Inspect administrative pages for unexpected script execution or HTML attribute injections.

Impact Analysis

Attackers could execute malicious scripts in the browsers of high-privilege users like administrators when they view affected pages. This could lead to session hijacking, unauthorized actions, or data theft if the admin has elevated permissions.

Compliance Impact

This vulnerability could compromise user data confidentiality and integrity, potentially violating GDPR (data protection) and HIPAA (health data security) requirements. Unauthorized script execution may lead to data breaches or unauthorized access, triggering compliance violations.

Mitigation Strategies

Update the RegistrationMagic plugin to version 6.0.9.9 or later immediately. Disable any affected form fields on registrant profile pages until the update is applied. Monitor administrative pages for unusual activity or unauthorized script execution.
