⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, compromise sensitive business data, or redirect users to phishing sites, potentially leading to full system compromise through privilege escalation.
Likely Case
Attackers inject malicious scripts to steal user session cookies, perform actions on behalf of authenticated users, or deface web interfaces.
If Mitigated
With proper input validation and output encoding, the vulnerability would be prevented, though the underlying code flaw remains.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity; exploitation likely requires user interaction (clicking malicious link).
