  "summary" : "ArcadeDB: IMPORT DATABASE allows SSRF and arbitrary local file read by authenticated users",
  "details" : "### Impact\n\nThe SQL `IMPORT DATABASE` statement did not require administrative privileges and passed its source URL to the importer without validation. Any authenticated user with SQL command access (not only `root`/administrators) could therefore:\n\n- **Server-Side Request Forgery (CWE-918):** cause the server to issue HTTP(S) requests to arbitrary destinations, including cloud metadata endpoints (e.g. `169.254.169.254`) and internal-only services, and ingest the responses as queryable records.\n- **Arbitrary local file read (CWE-22):** read local files reachable by the server process (e.g. `/etc/passwd`, credential files) by importing `file://` paths, exposing their contents as records.\n\nThe server administration endpoint (`/api/v1/server`) was already restricted to the `root` user and was **not** affected; the exposure was through the database SQL command/query endpoints (`/api/v1/command`, `/api/v1/query`).\n\nA related lower-severity hardening gap (CWE-776): the XML importer did not disable DTD processing, leaving entity-expansion (Billion Laughs) possible.\n\n### Affected component\n\n`integration/src/main/java/com/arcadedb/integration/importer/SourceDiscovery.java` (no host allow-list for http(s); no path validation for `file://`), reached from `engine/.../query/sql/parser/ImportDatabaseStatement.java`.\n\n### Patches\n\n- `IMPORT DATABASE` now requires the administrative `updateSecurity` permission (no-op in embedded mode).\n- Import sources are validated in `SourceDiscovery`: HTTP(S) hosts resolving to loopback / link-local / private (site-local) / wildcard / multicast addresses are blocked by default (`arcadedb.server.security.importBlockLocalNetworks`, default `true`), and an optional local-path allow-list (`arcadedb.server.security.importAllowedLocalPaths`) restricts `file://` reads.\n- The XML importer now disables DTD processing and external entities.\n\nFixed in commit referenced by pull request [#4422](https://github.com/ArcadeData/arcadedb/pull/4422).\n\n### Workarounds\n\nRestrict SQL command/query access to trusted administrative users; do not grant query access to untrusted users on servers that can reach sensitive networks or hold sensitive local files. Upgrading is strongly recommended.\n\n### Credit\n\nReported by Bin Luo (luob87709@gmail.com).",
