⚠️ Risk & Real-World Impact
Worst Case
Attackers could inject malicious JavaScript that steals administrator credentials, redirects users to phishing sites, or performs unauthorized administrative actions on the WordPress site.
Likely Case
Attackers create fake forms or links that trick administrators into unknowingly injecting malicious scripts, leading to session hijacking or defacement of the website.
If Mitigated
With proper CSRF tokens and input validation, the attack chain is broken and no malicious scripts can be injected.
🎯 Exploit Status
Exploitation requires tricking an authenticated administrator into clicking a malicious link or visiting a crafted page. The stored XSS payload then affects all users visiting the compromised page.
