📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, perform actions as authenticated users, deface websites, or redirect users to malicious sites.
Likely Case
Attackers with low privileges could steal session tokens from other users, perform limited unauthorized actions, or deploy credential harvesting forms.
If Mitigated
With proper input validation and output encoding, the impact is limited to unsuccessful injection attempts.
🎯 Exploit Status
Exploitation requires authenticated low-privileged access. The vulnerability is in form fields where user input is not properly sanitized.
