Authenticated host code execution via console prototype chain
Published Apr 13, 2026 · Updated Apr 13, 2026
Sandbox escape in NocoBase @nocobase/plugin-workflow-javascript 2.0.0 through 2.0.23 allows remote authenticated users to execute host code. createSafeConsole nulls constructors on bound console methods but leaves the host Function constructor reachable through their prototype chain. Exploitation requires control of a Workflow JavaScript node and grants access to the host Node.js process and its process-level resources.
