{"id":"GHSA-8w86-m9h8-hvqg","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).","aliases":["CVE-2026-54077"],"modified":"2026-07-16T20:26:44.480476Z","published":"2026-07-16T20:05:56Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-07-16T20:05:56Z","nvd_published_at":null,"cwe_ids":["CWE-22","CWE-776","CWE-918"]},"references":[{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/security/advisories/GHSA-8w86-m9h8-hvqg"},{"type":"PACKAGE","url":"https://github.com/ArcadeData/arcadedb"},{"type":"WEB","url":"https://github.com/ArcadeData/arcadedb/releases/tag/26.6.1"}],"affected":[{"package":{"name":"com.arcadedb:arcadedb-engine","ecosystem":"Maven","purl":"pkg:maven/com.arcadedb/arcadedb-engine"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"26.6.1"}]}],"versions":["21.10.1","21.10.2","21.11.1","21.12.1","21.9.1","21.9.1-beta","22.1.1","22.1.2","22.1.3","22.10.1","22.11.1","22.12.1","22.2.1","22.8.1","22.9.1","23.1.1","23.1.2","23.10.1","23.11.1","23.12.1","23.12.2","23.2.1","23.3.1","23.4.1","23.5.1","23.6.1","23.7.1","23.9.1","24.1.1","24.10.1","24.11.1","24.11.2","24.2.1","24.4.1","24.5.1","24.6.1","25.1.1","25.10.1","25.11.1","25.12.1","25.2.1","25.3.1","25.3.2","25.4.1","25.5.1","25.6.1","25.7.1","25.8.1","25.9.1","26.1.1","26.2.1","26.2.2","26.3.1","26.3.2","26.4.2","26.5.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-8w86-m9h8-hvqg/GHSA-8w86-m9h8-hvqg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L"}]}
