⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals administrator credentials, defaces websites, or installs backdoors when administrators view compromised pages.
Likely Case
Attackers inject malicious scripts that steal user session cookies or redirect users to phishing sites when they visit pages containing the injected content.
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 visiting a malicious page. The CSRF leads to stored XSS payload injection.
