{"id":"GHSA-j5h6-vqc3-phqh","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 `\u003c= 12.0.0` (confirmed on `directus/directus:latest`, v11.17.3, with default configuration)\n- **Patched:** Directus `\u003e= 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.","aliases":["CVE-2026-61835"],"modified":"2026-07-20T22:00:25.303443496Z","published":"2026-07-20T21:47:17Z","database_specific":{"nvd_published_at":"2026-07-15T15:16:48Z","cwe_ids":["CWE-918"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-20T21:47:17Z"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/directus/directus/pull/27606"},{"type":"WEB","url":"https://github.com/directus/directus/commit/f75b25fa44b05c6022b20f231c20bc6e50f021d7"},{"type":"PACKAGE","url":"https://github.com/directus/directus"},{"type":"WEB","url":"https://github.com/directus/directus/releases/tag/v12.0.0"}],"affected":[{"package":{"name":"directus","ecosystem":"npm","purl":"pkg:npm/directus"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"12.0.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-j5h6-vqc3-phqh/GHSA-j5h6-vqc3-phqh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
