⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals administrator credentials, redirects users to phishing sites, or takes full control of the WordPress site when administrators view infected pages.
Likely Case
Attackers create phishing pages that trick logged-in administrators into unknowingly executing actions that inject malicious scripts into the site, potentially compromising visitor data or site integrity.
If Mitigated
With proper CSRF tokens and input validation, the attack chain would be broken at the initial CSRF stage, preventing the stored XSS payload from being injected.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users, but the technical execution is straightforward once the user is tricked.
