Report: CVE-2026-34156 - NocoBase Affected by Sandbox Escape to RCE via console._stdout Prototype Chain T
CVE ID :CVE-2026-34156 Published : March 31, 2026, 1:33 p.m. | 29 minutes ago Description :NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.28, NocoBase's Workflow Script Node executes user-supplied JavaScript inside a Node.js vm sandbox with a custom require allowlist (controlled by WORKFLOW_SCRIPT_MODULES env var). However, the console object passed into the sandbox context exposes host-realm WritableWorkerStdio stream objects via console._stdout and console._stderr. An authenticated attacker can traverse the prototype chain to escape the sandbox and achieve Remote Code Execution as root. This issue has been patched in version 2.0.28.
