⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative privileges, compromise all user accounts, exfiltrate sensitive CRM data, and potentially pivot to other systems.

🎯 Exploit Status
Exploitation requires authenticated access but is straightforward via parameter manipulation in profile update requests.
