Summary

Ghost, a Node.js content management system, is affected from 0.7.2 before 6.64.0. An observable discrepancy (CWE-203) lets any staff-level user determine the relative ordering of other staff users' hashed passwords. The hashes themselves are not disclosed, and the advisory describes no practical path to recovering a password. An attacker needs network access and low privileges, with high attack complexity.

Description from the CNA

Ghost is a Node.js content management system. From 0.7.2 until 6.64.0, any staff-level user was able to determine the relative ordering of other staff users' hashed passwords. This does not directly disclose password hashes, and does not provide a practical path to recovering a password. This issue is fixed in version 6.64.0.
