GHSA-fpg6-x68q-5793
GHSA-fpg6-x68q-5793 is a OS Command Injection vulnerability in n8n. O3 Security confirms whether GHSA-fpg6-x68q-5793 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
n8nnpmDescription
Impact
The shell tool in the @n8n/computer-use package applied its sandbox restrictions only on macOS. On Linux and Windows, shell commands executed by the tool ran without any filesystem or network restrictions, allowing unrestricted access to the host filesystem and network from within the computer-use agent process.
This issue only affects deployments where the @n8n/computer-use package is explicitly installed and running. It does not affect standard n8n installations.
Patches
The issue has been fixed in n8n versions 2.29.8 and 2.30.1. Users should upgrade to one of these versions or later to remediate the vulnerability.
The fix adds sandbox enforcement on Linux via bubblewrap and disables the shell tool entirely when a working sandbox cannot be established. An explicit opt-out flag (--dangerously-disable-shell-sandbox) is available for deployments that require unsandboxed shell access and accept the associated risk.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Disable or avoid deploying the
@n8n/computer-usepackage on Linux or Windows hosts until the fix is applied. - Restrict access to the n8n instance and the computer-use agent to fully trusted users only.
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 2.30.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fpg6-x68q-5793 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-fpg6-x68q-5793 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-fpg6-x68q-5793. 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-fpg6-x68q-5793 in your dependencies?
O3 detects GHSA-fpg6-x68q-5793 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
