Description

Ghost from 0.7.2 before 6.64.0 contains an information disclosure vulnerability in the Admin API that allows staff-level users to determine the relative ordering of other staff users' password hashes. Authenticated staff users can query the Admin API to infer hash ordering, though this does not directly reveal hashes or enable practical password recovery.
