🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Stored XSS vulnerabilities typically require some level of access to input fields, but once injected, the payload executes automatically for all users viewing the affected page.
