⚠️ Risk & Real-World Impact
Worst Case
Attackers could compromise administrator accounts, inject persistent malware into websites, steal session cookies, redirect users to malicious sites, or deface the website.
Likely Case
Attackers inject malicious JavaScript that steals user session cookies or credentials when administrators visit vulnerable pages, leading to account takeover.
If Mitigated
With proper CSRF tokens and input validation, the attack vector is eliminated, preventing unauthorized actions and script injection.
🎯 Exploit Status
Exploitation requires tricking an authenticated user (typically an administrator) to click a malicious link or visit a crafted page. The CSRF leads to stored XSS payload injection.
