{"id":"BIT-ghost-2026-53949","summary":"Ghost Content API filter bypass reveals private fields","details":"Ghost is a Node.js content management system. From 5.46.1 until 6.21.2, the validation applied to filters on the public API endpoints could be partially bypassed, making it possible to reveal private fields via a brute force attack. If SQLite was used as the database password hashes were fully accessible. If MySQL was used as the database the password hashes' case (uppercase / lowercase) would have been lost, which would likely have rendered a further brute force attack on the discovered hashes fruitless. This vulnerability is fixed in 6.21.2.","aliases":["CVE-2026-53949","GHSA-jx35-x7fj-vgpr"],"modified":"2026-07-08T08:26:36.423539146Z","published":"2026-06-30T23:39:26.128Z","database_specific":{"cpes":["cpe:2.3:a:ghost:ghost:*:*:*:*:*:node.js:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jx35-x7fj-vgpr"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53949"}],"affected":[{"package":{"name":"ghost","ecosystem":"Bitnami","purl":"pkg:bitnami/ghost"},"ranges":[{"type":"SEMVER","events":[{"introduced":"5.46.1"},{"fixed":"6.21.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/ghost/BIT-ghost-2026-53949.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.5"}
