⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, compromise WordPress admin accounts, install backdoors, or redirect users to phishing sites, potentially leading to complete site takeover.
Likely Case
Attackers would typically use this to steal user session cookies or credentials, perform actions on behalf of authenticated users, or redirect to malicious sites for further exploitation.
If Mitigated
With proper Content Security Policy headers and input validation, the impact is limited to potential script execution in user browsers without direct server compromise.
🎯 Exploit Status
Exploitation requires social engineering to trick users into clicking malicious links, but the technical complexity of the XSS injection itself is low.
