{"id":"CVE-2026-70590","published":"2026-08-04T22:17:16.850","lastModified":"2026-08-05T15:17:14.750","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.","cvssScore":4.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:H/A:N","cwes":["CWE-200"],"vendors":[],"products":[],"references":[{"url":"https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00","tags":[]},{"url":"https://github.com/TryGhost/Ghost/pull/29628","tags":[]},{"url":"https://github.com/TryGhost/Ghost/releases/tag/v6.54.1","tags":[]},{"url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jm22-3w23-5q7w","tags":[]}],"exploitRefs":[{"url":"https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00","tags":[]},{"url":"https://github.com/TryGhost/Ghost/pull/29628","tags":[]},{"url":"https://github.com/TryGhost/Ghost/releases/tag/v6.54.1","tags":[]},{"url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jm22-3w23-5q7w","tags":[]}],"hasPoc":true,"ai":null}
