📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface websites, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Attackers with low privileges could steal session cookies, perform actions as authenticated users, or conduct phishing attacks against other users.
If Mitigated
With proper input validation and output encoding, the risk is limited to potential data exposure from successful exploitation attempts.
🎯 Exploit Status
Requires authenticated low-privileged access to vulnerable form fields
