{"id":"CVE-2026-70590","aliases":["BIT-ghost-2026-70590","GHSA-jm22-3w23-5q7w"],"url":"https://o3.security/vulnerability/CVE-2026-70590","summary":"Ghost: Blind Password Hash Disclosure in Ghost Admin API","details":"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":"2026-08-04T21:27:22.823Z","modified":"2026-09-10T03:30:44.095065496Z","cvss":{"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"},"epss":{"score":0.00195,"percentile":0.095,"asOf":"2026-08-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"ghost","fixedVersion":"6.54.1"}],"fix":{"url":"https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00","label":"TryGhost/Ghost@63c31fa"},"references":[{"type":"WEB","url":"https://github.com/TryGhost/Ghost/releases/tag/v6.54.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70590.json"},{"type":"ADVISORY","url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jm22-3w23-5q7w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70590"},{"type":"FIX","url":"https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00"},{"type":"FIX","url":"https://github.com/TryGhost/Ghost/pull/29628"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:30:44.095065496Z"}}
