⚠️ 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 fake requests that trick administrators into adding malicious scripts to the site, potentially compromising user sessions and site integrity.
If Mitigated
With proper CSRF tokens and input validation, the attack chain would be broken, preventing both the CSRF and subsequent XSS.
🎯 Exploit Status
CSRF to XSS chain is well-understood attack pattern. Exploitation requires social engineering to trick authenticated users.
