⚠️ Risk & Real-World Impact

🔴

Worst Case

Privileged user steals authentication credentials from headers, leading to lateral movement, data exfiltration, or complete system compromise.

🟠

Likely Case

Privileged user accesses sensitive authentication information, potentially enabling unauthorized access to other systems or data.

🟢

If Mitigated

Limited impact due to proper access controls, monitoring, and separation of duties preventing misuse of privileged access.

🌐 Internet-Facing: LOW with brief explanation
🏢 Internal Only: MEDIUM with brief explanation

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW
