⚠️ Risk & Real-World Impact
Worst Case

Likely Case
Malicious administrators or compromised admin accounts inject tracking scripts, deface content, or steal limited user data from visitors viewing affected pages.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before reaching users, preventing execution while maintaining functionality.
