CVE-2026-70590

Ghost: Blind Password Hash Disclosure in Ghost Admin API

Published Aug 4, 2026 CVSS 3.1 · 4.8 Medium EPSS < 1% KEV · Not listed
Description
Ghost is a Node.js content management system. Prior to 6.54.1, any staff-level user was able to leak the hashed passwords of other staff users through the Ghost Admin API. An offline password-guessing attack against the hashes could lead to account takeover if successful, but Device Verification should have prevented an attacker from logging in with a recovered password. Depending on the database used, leaked hashes may not have had the correct casing for all characters, increasing the difficulty of a password-guessing attack. This issue is fixed in version 6.54.1.
