SCA: security update for @nocobase/plugin-workflow-javascript (GHSA-px3p-vgh9-m57c)

critical Tenable Cloud Security Plugin ID 439472

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-34156)

Solution

Update the @nocobase/plugin-workflow-javascript library and its related packages to version 2.0.28 or later.
