Incorrect Authorization
CVE-2026-44221
Summary
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 authorization could be bypassed by any authenticated principal. This affects arcade-db versions prior to 26.4.2.

CWE-863 - Incorrect Authorization
Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
