ArcadeDB server (com.arcadedb:arcadedb-server) in versions 26.7.3 and earlier fails to propagate the authenticated principal to asynchronous command worker threads. When an HTTP command is submitted with awaitResponse:false, it executes on an async worker whose DatabaseContext has no bound user, causing the scripting authorization gate to become a no-op. A user with only read access to a single database can submit an asynchronous JavaScript (language=js) command via the /api/v1/command endpoint to run code with unrestricted host access (e.g., database.getSecurity().createUser) and create a server-wide administrator, escalating to full administrative control. Fixed in 26.8.1.
