Advisories for Maven/Com.arcadedb/Arcadedb-Server package

A user holding only reader (read-only) privileges on a single database could execute arbitrary JVM code by sending a "language": "js" command to the POST /api/v1/command/{database} HTTP endpoint, and use it to read arbitrary files on the host filesystem (e.g. /etc/passwd, configuration files), outside the scope of the database itself. Two cooperating defects made this possible: Missing authorization on the scripting path (CWE-863 / CWE-269). Polyglot script execution (js and …

About 14 HTTP handlers resolve the {database} path param and call getDatabase(…) WITHOUT user.canAccessToDatabase(…) and without setting the engine principal, because they extend AbstractServerHttpHandler directly instead of DatabaseAbstractHandler (which holds the only per-database gate at DatabaseAbstractHandler.java:69,88-90). Affected: PostBatchHandler:129, PostTimeSeriesWriteHandler:115, PostPrometheusWriteHandler:83, PostTimeSeriesQueryHandler:69, GetTimeSeriesLatestHandler:58, PostGrafanaQueryHandler:69, GetGrafanaHealthHandler:49, GetGrafanaMetadataHandler:52, GetPromQLQueryHandler:63, GetPromQLQueryRangeHandler:71, GetPromQLLabelsHandler:56, GetPromQLLabelValuesHandler:62, GetPromQLSeriesHandler:72, PostPrometheusReadHandler:85. The engine fallback is also void: LocalDatabase.checkPermissionsOnDatabase:711 early-returns when getCurrentUser()==null. Exploit: a user authorized only for DB 'a' calls …

Authenticated users and API tokens scoped to a specific database could read, write, and mutate schema on any other database on the same server. Two distinct defects contributed: (1) ServerSecurityUser.getDatabaseUser() returned a DB user with an uninitialized fileAccessMap, which requestAccessOnFile treated as allow-all; (2) ArcadeDBServer.createDatabase() omitted factory.setSecurity(…) so any database created via POST /api/v1/server {"command":"create database X"} had its entire record-level authorization system silently disabled. In combination, record-level and database-level …
