⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal administrator credentials, hijack user sessions, perform actions as authenticated users, and potentially gain full control of the application.

🟠

Likely Case

Authenticated attackers could steal session cookies or credentials from other users, leading to unauthorized access and data exposure.

🟢

If Mitigated

With proper input validation and output encoding, the risk is limited to authenticated users only, reducing the attack surface.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
