⚠️ 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.

🟠

Likely Case

🌐 Internet-Facing: HIGH
🏢 Internal Only: LOW

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires tricking an administrator into clicking a malicious link while authenticated. The CSRF leads to stored XSS payload injection.
