{"id":"CVE-2026-70590","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-70590","generatedAt":"2026-10-28T06:14:21.030Z","title":"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.","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.","published":"2026-08-04T22:17:17.000Z","lastModified":"2026-10-24T15:10:00.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:H/A:N"},"cwe":["CWE-200"],"affected":[],"epss":{"score":0.00323,"percentile":0.25204,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.32%).
