⚠️ 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 through stored XSS payloads.

🟠

Likely Case

Attackers create fake maintenance pages with malicious scripts that steal session cookies or redirect users to malicious sites when they visit the affected WordPress pages.

🟢

If Mitigated

With proper CSRF tokens and input validation, the attack would fail at the initial CSRF stage, preventing XSS injection entirely.
