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.","state":0,"publishedAt":"2026-06-24T19:17:12.58+00:00","modifiedAt":"2026-10-25T22:10:00.15+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/TryGhost/Ghost/security/advisories/GHSA-jx35-x7fj-vgpr"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53949","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-200","CWE-693"],"productCriteria":[],"sourceDates":{"published":"2026-06-24T19:17:12.580","lastModified":"2026-10-25T22:10:00.150"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
