NocoBase - VM Sandbox Escape to Remote Code Execution

NocoBase Workflow Script Node executes user-supplied JavaScript inside a Node.js vm sandbox with a custom require allowlist controlled by WORKFLOWSCRIPTMODULES env var. The console object passed into the sandbox context exposes host-realm WritableWorkerStdio stream objects via console.stdout and...

CVE-2026-77077

n8n versions before 1.123.69, 2.33.4, and 2.34.1 contain a JavaScript task runner VM sandbox escape. The runner's prototype-freezing routine covers globalThis functions but not internal module constructors such as EventEmitter, allowing an authenticated user with Code node access to exploit...

CVE-2026-77077

n8n versions before 1.123.69, 2.33.4, and 2.34.1 have a VM sandbox escape in the task runner: the prototype-freezing routine misses internal constructors like EventEmitter, allowing an authenticated user with Code node access to pollute prototypes and execute arbitrary commands. The corruption is...
