CyberRota Analysis

AI-Generated

The ArcadeDB server in versions 26.7.3 and earlier is vulnerable due to improper handling of authenticated principals in asynchronous command execution, allowing users with read-only access to escalate their privileges and gain full administrative control by executing arbitrary JavaScript commands. This critical vulnerability poses a significant risk to any organization using affected versions, particularly those with sensitive data or operational dependencies on the database. Users should prioritize upgrading to version 26.8.1 or later to mitigate this risk.

Original NVD Description

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.
