GHSA-44v6-jhgm-p3m4

HIGH

GHSA-44v6-jhgm-p3m4 is a high-severity (CVSS 7.5) remote code execution vulnerability in n8n. O3 Security confirms whether GHSA-44v6-jhgm-p3m4 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Impact

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 issue only affects instances where the Python Task Runner is enabled.

Patches

The issue has been fixed in n8n versions 1.123.32, 2.17.4, and 2.18.1. Users should upgrade to one of these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

  • Limit workflow creation and editing permissions to fully trusted users only.
  • Disable the Python Code node by adding n8n-nodes-base.code to the NODES_EXCLUDE environment variable, or disable the Python Task Runner entirely.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update n8n to 1.123.32 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-44v6-jhgm-p3m4 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-44v6-jhgm-p3m4 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-44v6-jhgm-p3m4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
