{"id":"CVE-2023-31133","aliases":["BIT-ghost-2023-31133","GHSA-r97q-ghch-82j9"],"url":"https://o3.security/vulnerability/CVE-2023-31133","summary":"Ghost vulnerable to disclosure of private API fields","details":"Ghost is an app for new-media creators with tools to build a website, publish content, send newsletters, and offer paid subscriptions to members. Prior to version 5.46.1, due to a lack of validation when filtering on the public API endpoints, it is possible to reveal private fields via a brute force attack.\n\nGhost(Pro) has already been patched. Maintainers can find no evidence that the issue was exploited on Ghost(Pro) prior to the patch being added. Self-hosters are impacted if running Ghost a version below v5.46.1. v5.46.1 contains a fix for this issue. As a workaround, add a block for requests to `/ghost/api/content/*` where the `filter` query parameter contains `password` or `email`.","published":"2023-05-08T20:56:39.299Z","modified":"2026-08-08T03:47:39.835597253Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"ghost","fixedVersion":"5.46.1"}],"fix":{"url":"https://github.com/TryGhost/Ghost/commit/b3caf16005289cc9909488391b4a26f3f4a66a90","label":"TryGhost/Ghost@b3caf16"},"references":[{"type":"WEB","url":"https://github.com/TryGhost/Ghost/releases/tag/v5.46.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/31xxx/CVE-2023-31133.json"},{"type":"ADVISORY","url":"https://github.com/TryGhost/Ghost/security/advisories/GHSA-r97q-ghch-82j9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-31133"},{"type":"FIX","url":"https://github.com/TryGhost/Ghost/commit/b3caf16005289cc9909488391b4a26f3f4a66a90"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:47:39.835597253Z"}}
