Vulnerability details
The vulnerability allows a remote user to disclose password hashes of other staff users.
The vulnerability exists due to observable discrepancy in the Ghost Admin API when handling staff-level administrative requests. A remote user can access crafted API interactions to disclose password hashes of other staff users.
