📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
A malicious privileged user could embed JavaScript that steals administrator credentials, leading to complete system compromise and data exfiltration.
Likely Case
Privileged user injects JavaScript that captures session cookies or credentials of other users viewing the compromised interface.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be neutralized before execution.
🎯 Exploit Status
Exploitation requires authenticated privileged access; XSS payloads are well-documented and easy to craft
