Prior to 11.17.0, the PATCH /files/{id} endpoint accepts a user-controlled filename_disk parameter. By setting this value to match the storage path of another user's file, an attacker can overwrite that file's content while manipulating metadata fields such as uploaded_by to obscure the tampering. This vulnerability is fixed in 11.17.0.","published":"2026-04-09T16:07:54.100Z","modified":"2026-08-05T03:32:15.455011291Z","cvss":{"score":8.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"directus","fixedVersion":"11.17.0"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/directus/directus/releases/tag/v11.17.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39942.json"},{"type":"ADVISORY","url":"https://github.com/directus/directus/security/advisories/GHSA-393c-p46r-7c95"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39942"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:32:15.455011291Z"}}
