⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals admin credentials, redirects users to phishing sites, or takes over administrative accounts, potentially leading to complete site compromise.
Likely Case
Attackers inject malicious scripts that display unwanted content, redirect users to malicious sites, or steal session cookies from logged-in users.
If Mitigated
With proper CSRF protections and content security policies, the attack surface is reduced, though the vulnerability still exists in the codebase.
🎯 Exploit Status
Exploitation requires tricking an authenticated user (typically an administrator) into performing a malicious action, but no authentication is needed for the CSRF attack itself once the user is tricked.
