⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal administrator credentials, take over WordPress sites, install backdoors, deface websites, or redirect users to malicious sites, potentially leading to complete site compromise and data breaches.

🟠

Likely Case

Attackers inject malicious JavaScript to steal user session cookies, redirect users to phishing pages, or perform actions on behalf of authenticated users, leading to account compromise and unauthorized access.

🟢

If Mitigated

With proper input validation and output encoding, the injected scripts would be rendered harmless as text rather than executable code, preventing exploitation.

🌐 Internet-Facing: HIGH
