⚠️ Risk & Real-World Impact
Worst Case
Complete site takeover through persistent XSS payloads that steal admin credentials, deface websites, or redirect visitors to malicious sites.
Likely Case
Attackers inject malicious JavaScript that steals session cookies, performs unauthorized actions, or displays unwanted content to visitors.
If Mitigated
Limited impact with proper CSRF tokens and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users. CSRF leads to stored XSS payload injection.
