Upgrade n8n-nodes-base to version 2.3.0 or higher.
Overview
n8n-nodes-base is a Base nodes of n8n
Affected versions of this package are vulnerable to Protection Mechanism Failure via the Python Code node. An attacker can execute arbitrary code outside the intended security boundary by leveraging authenticated access and enabling Task Runners with Python support. This is only exploitable if Task Runners are enabled (N8N_RUNNERS_ENABLED=true), Python support is enabled (N8N_PYTHON_ENABLED=true), and the Code Node is enabled (default: true).
Workaround
This vulnerability can be mitigated by disabling the Code Node via the NODES_EXCLUDE environment variable or running Task Runners in external mode to isolate untrusted code execution in a separate sidecar container.
