An offline password-guessing attack against the hashes could lead to account takeover if successful, but [Device Verification](https://docs.ghost.org/security#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.\n\n### Vulnerable versions\n\nThis vulnerability is present in Ghost versions v6.54.0 and earlier.\n\n### Patches\n\nv6.54.1 contains a fix for this issue.\n\n### How to update\n\nFor self-hosters using Docker, find [Docker's official Ghost image here](https://hub.docker.com/_/ghost). Updating a Docker-based Ghost instance [is documented here](https://docs.ghost.org/install/docker#updating-ghost). \n\nIf your Ghost is a Ghost-CLI install see our documentation on [updating it to the latest version here](https://docs.ghost.org/update). \n\n### Workarounds\n\nIf upgrading immediately is not possible, ensure all staff users have [Multi-factor Authentication](https://docs.ghost.org/security#email-2fa) (MFA) enabled. This will help prevent an attacker from logging in with any passwords that are successfully recovered from the leaked hashes.\n\n### References\n\nGhost thanks Chapman Schleiss for disclosing this vulnerability responsibly. \n\n### For more information\n\nIf you have any questions or comments about this advisory, email us at [security@ghost.org](mailto:security@ghost.org).","state":0,"publishedAt":"2026-08-04T21:28:35+00:00","modifiedAt":"2026-08-17T08:10:38.6235239+00:00","affected":[{"ecosystem":"npm","name":"ghost","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"6.54.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/TryGhost/Ghost/security/advisories/GHSA-jm22-3w23-5q7w","https://github.com/TryGhost/Ghost/pull/29628","https://github.com/TryGhost/Ghost/commit/63c31fad7e473caa62d8fbb4651a04a2a62b5d00","https://github.com/TryGhost/Ghost","https://github.com/TryGhost/Ghost/releases/tag/v6.54.1"],"sourceUrl":"https://github.com/advisories/GHSA-jm22-3w23-5q7w","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-jm22-3w23-5q7w","identifiers":["GHSA-jm22-3w23-5q7w","BIT-ghost-2026-70590","CVE-2026-70590"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
