⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals administrator credentials, redirects users to malicious sites, or defaces the website persistently for all visitors.
Likely Case
Attackers create fake admin actions that inject advertising scripts, cryptocurrency miners, or credential-stealing payloads into vulnerable pages.
If Mitigated
With proper CSRF tokens and input validation, the attack chain would be broken, preventing both the CSRF and subsequent XSS.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users. The CSRF leads to stored XSS, making the attack persistent.
