⚠️ Risk & Real-World Impact
Worst Case
Complete site takeover through persistent XSS payloads that steal administrator credentials, deface websites, or redirect visitors to malicious sites.
Likely Case
Attackers inject malicious JavaScript that steals session cookies, performs unauthorized actions, or displays fraudulent content to users.
If Mitigated
Limited impact with proper CSRF tokens and Content Security Policy (CSP) headers in place, though stored XSS payloads may still execute if previously injected.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users, but the technical complexity is low once the user is tricked.
