GHSA-44v6-jhgm-p3m4
HIGHGHSA-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.

n8nnpmDescription
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.codeto theNODES_EXCLUDEenvironment 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 dependencyDetect
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.
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.
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.
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.
Frequently Asked Questions
Is GHSA-44v6-jhgm-p3m4 in your dependencies?
O3 detects GHSA-44v6-jhgm-p3m4 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
