⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject persistent malicious scripts that steal session cookies, redirect users to phishing sites, or perform administrative actions on the WordPress site, potentially leading to complete site compromise.
Likely Case
Attackers inject malicious JavaScript that steals user session cookies or credentials when users visit compromised pages, leading to account takeover and unauthorized content modification.
If Mitigated
With proper CSRF tokens and input validation, the attack chain is broken, preventing unauthorized actions and script injection.
🎯 Exploit Status
Exploitation requires tricking an authenticated user into visiting a malicious page. The CSRF leads to stored XSS payload injection.
