{"id":"CVE-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":["GHSA-jx35-x7fj-vgpr"],"modified":"2026-06-26T11:56:51.943281955Z","published":"2026-06-24T18:05:29.100Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53949.json","cwe_ids":["CWE-200","CWE-693"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53949.json"},{"type":"ADVISORY","url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-jx35-x7fj-vgpr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53949"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tryghost/ghost","events":[{"introduced":"17025cd344e2cded3aae69416281826606d07d1d"},{"fixed":"b8cf9d9beb9854466b5a2ebb85ad40a290daf68b"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"5.46.1"},{"fixed":"6.21.2"}]}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53949.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
