⚠️ Risk & Real-World Impact
Worst Case

Likely Case
Account takeover of known users, potentially leading to data theft, privilege escalation to admin if admin email is known, or unauthorized access to sensitive functionality.
If Mitigated
Limited impact if proper network segmentation, strong authentication controls, and monitoring are in place to detect unauthorized access attempts.
🎯 Exploit Status
Exploitation requires knowing a user's email address but is otherwise straightforward via the vulnerable REST endpoint.
