CVE-2026-104415: Observable Discrepancy in TryGhost Ghost
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.
AI Analysis
Technical Summary
CVE-2026-104415 is an information disclosure vulnerability in the Admin API of Ghost software versions >=0.7.2 and <6.64.0. It allows authenticated staff-level users to infer the relative ordering of other staff users' password hashes. This leakage does not reveal the hashes themselves nor does it facilitate practical password recovery or direct compromise of credentials.
Potential Impact
The vulnerability allows staff-level users to gain limited information about the relative ordering of password hashes of other staff users. However, it does not disclose the actual password hashes or enable attackers to recover passwords. The impact is therefore limited to minor information disclosure with low severity.
Mitigation Recommendations
A fix is available in Ghost version 6.64.0 and later. Users should upgrade to version 6.64.0 or newer to remediate this vulnerability.
