⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could inject malicious JavaScript that steals administrator credentials, redirects users to malicious sites, or takes full control of the WordPress site when administrators visit compromised pages.

🟠

Likely Case

Attackers inject tracking scripts, deface content, or steal session cookies from administrators who visit pages with the injected payload.

🟢

If Mitigated

With proper CSRF tokens and Content Security Policy (CSP), the attack would fail or be limited to non-persistent effects.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM
