Publication date: 2026-06-23

Last updated on: 2026-06-23

Assigner: GitHub, Inc.

Description
n8n is an open source workflow automation platform. Prior to 1.123.48, 2.21.8, and 2.22.4, an authenticated user with permission to create or modify workflows containing a Python Code Node could escape the sandbox and achieve arbitrary code execution on the task runner container. This vulnerability is fixed in 1.123.48, 2.21.8, and 2.22.4.

Executive Summary

This vulnerability affects the n8n workflow automation platform versions prior to 1.123.48, 2.21.8, and 2.22.4. An authenticated user who has permission to create or modify workflows that include a Python Code Node can escape the sandbox environment designed to restrict code execution. By doing so, the user can execute arbitrary code on the task runner container, potentially gaining unauthorized control over the system running the workflows.

Impact Analysis

The impact of this vulnerability is that an attacker with limited permissions could execute arbitrary code on the container running the workflows. This could lead to unauthorized access, data manipulation, disruption of services, or further compromise of the environment hosting the n8n platform.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade n8n to one of the fixed versions: 1.123.48, 2.21.8, or 2.22.4.

This vulnerability allows an authenticated user with permission to create or modify workflows containing a Python Code Node to escape the sandbox and execute arbitrary code on the task runner container. Applying the update will fix this issue.
