⚠️ 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 through persistent XSS payloads.
Likely Case
Attackers create fake forms or links that trick logged-in administrators into unknowingly submitting malicious requests, leading to stored XSS payloads being injected into the site.
If Mitigated
With proper CSRF tokens and input validation, the vulnerability would be prevented as legitimate requests would be properly authenticated and sanitized.
🎯 Exploit Status
Exploitation requires social engineering to trick authenticated users. The CSRF leads to stored XSS, making it a two-stage attack.
