{"id":"CVE-2026-61835","aliases":["GHSA-j5h6-vqc3-phqh"],"url":"https://o3.security/vulnerability/CVE-2026-61835","summary":"Directus: SSRF Protection Bypass via 0.0.0.0 in File Import","details":"### Summary\n\nThe SSRF protection on Directus's file-import-from-URL feature can be bypassed using the address `0.0.0.0`. While `127.0.0.1` and other internal addresses are denied, `0.0.0.0` is not added to the blocklist. On Linux and macOS, connecting to `0.0.0.0` reaches localhost, so an authenticated user with file-upload rights can make the server fetch internal services and retrieve the response as a downloadable file (full-read SSRF).\n\n### Affected Versions\n\n- **Affected:** Directus `<= 12.0.0` (confirmed on `directus/directus:latest`, v11.17.3, with default configuration)\n- **Patched:** Directus `>= 12.0.0`\n\n### Details\n\nDirectus uses a deny-list config, `IMPORT_IP_DENY_LIST`, whose default value is `['0.0.0.0', '169.254.169.254']`.\n\nThe issue is in how `api/src/request/is-denied-ip.ts` processes this list. When it encounters the entry `0.0.0.0`, it treats it as a special keyword meaning \"block all local network interfaces,\" but it never blocks the literal address `0.0.0.0` itself. The handler sets the network-interface flag and skips to the next entry without adding `0.0.0.0` to the blocklist.\n\nWhat actually gets blocked is the loopback subnet `127.0.0.0/8` (from the `lo` interface) plus whatever addresses are assigned to the machine's network interfaces. The address `0.0.0.0` is not inside `127.0.0.0/8`; it belongs to the separate `0.0.0.0/8` range. So a request to `http://0.0.0.0:8055/` passes the blocklist check as \"allowed.\"\n\nAt the OS level, however, connecting to `0.0.0.0` reaches localhost, functionally equivalent to `127.0.0.1`. The same gap applies to the IPv6 unspecified address `::`. As a result, the SSRF protection is bypassed.\n\n### Impact\n\nAn authenticated user with create permission on `directus_files` (file-upload rights) can make the server issue requests to its own localhost via the `/files/import` endpoint. The response body is stored as a downloadable file, making this a full-read SSRF. On bare-metal or single-host deployments, this can reach databases, caches, and internal APIs bound to localhost. This bypass defeats the protections tracked as CVE-2026-35409 and CVE-2024-46990.","published":"2026-07-15T14:16:11.524Z","modified":"2026-08-12T03:51:17.415307761Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":{"score":0.00407,"percentile":0.34531,"asOf":"2026-09-16"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"directus","fixedVersion":"12.0.0"}],"fix":{"url":"https://github.com/directus/directus/commit/f75b25fa44b05c6022b20f231c20bc6e50f021d7","label":"directus/directus@f75b25f"},"references":[{"type":"WEB","url":"https://github.com/directus/directus/releases/tag/v12.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61835.json"},{"type":"ADVISORY","url":"https://github.com/directus/directus/security/advisories/GHSA-j5h6-vqc3-phqh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61835"},{"type":"FIX","url":"https://github.com/directus/directus/commit/f75b25fa44b05c6022b20f231c20bc6e50f021d7"},{"type":"FIX","url":"https://github.com/directus/directus/pull/27606"},{"type":"PACKAGE","url":"https://github.com/directus/directus"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.415307761Z"}}
