Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) flaw in the Church Admin WordPress plugin. It allows authenticated attackers with subscriber-level access or higher to inject malicious scripts via the 'email' parameter. The issue arises due to insufficient input sanitization and output escaping in versions up to 5.1.2.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the Church Admin plugin versions up to 5.1.2. Check for unauthorized script injections in the 'email' parameter fields. Review subscriber-level user activity logs for suspicious input patterns.

Impact Analysis

An attacker could exploit this to inject scripts that run when users access infected pages. This could lead to theft of cookies, session tokens, or other sensitive data. It may also allow unauthorized actions on behalf of users or defacement of the website.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR's integrity and confidentiality requirements. For HIPAA, it may expose protected health information, risking non-compliance with security rules. Both standards require safeguards against unauthorized data access or modification.

Mitigation Strategies
  • Update the Church Admin plugin to the latest version beyond 5.1.2 immediately.
  • Remove or disable the plugin if updates are unavailable.
  • Audit user roles with subscriber-level access for unauthorized changes.
  • Scan WordPress sites for stored XSS payloads in email fields.
