{"id":"BIT-ghost-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.","aliases":["CVE-2026-70590","GHSA-jm22-3w23-5q7w"],"modified":"2026-08-17T08:10:38.623523945Z","published":"2026-08-17T05:40:58.488Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:ghost:ghost:*:*:*:*:*:node.js:*:*"]},"references":[{"type":"WEB","url":"https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00"},{"type":"WEB","url":"https://github.com/TryGhost/Ghost/pull/29628"},{"type":"WEB","url":"https://github.com/TryGhost/Ghost/releases/tag/v6.54.1"},{"type":"WEB","url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jm22-3w23-5q7w"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70590"}],"affected":[{"package":{"name":"ghost","ecosystem":"Bitnami","purl":"pkg:bitnami/ghost"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"6.54.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/ghost/BIT-ghost-2026-70590.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:H/A:N"}]}],"schema_version":"1.9.0"}
