⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, gain administrative access to the WordPress site, install backdoors, deface the site, or steal sensitive user data.
Likely Case
Attackers inject malicious JavaScript to steal user session cookies, redirect users to phishing sites, or perform actions on behalf of authenticated users.
If Mitigated
With proper input validation and output encoding, malicious scripts would be neutralized before being stored or displayed to users.
🎯 Exploit Status
Exploitation requires the attacker to have some level of access to inject malicious scripts, but once stored, the payload executes when users view affected pages.
