⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, take over the WordPress site, install backdoors, deface the website, or use the compromised site to attack visitors.
Likely Case
Attackers inject malicious JavaScript to steal user session cookies, redirect users to phishing sites, or perform actions as authenticated users.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be rendered harmless as text rather than executable code.
🎯 Exploit Status
Stored XSS vulnerabilities typically require some level of user interaction or authenticated access to inject the payload, but once stored, the payload executes automatically for all users viewing the affected page.
