GHSA-2vx9-7wpg-88jq
MEDIUMGHSA-2vx9-7wpg-88jq is a medium-severity (CVSS 6.4) Path Traversal vulnerability in n8n. O3 Security confirms whether GHSA-2vx9-7wpg-88jq 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.
How urgent is this, really
GHSA-2vx9-7wpg-88jq plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 0 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
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 ExecuteWorkflow node's localFile source option read workflow files from disk without applying checks enforced by other file-reading nodes. An authenticated user with permission to create or modify workflows could supply an arbitrary file path via the REST API, bypassing the N8N_RESTRICT_FILE_ACCESS_TO restriction. This allowed the attacker to determine whether arbitrary files exist on the server host. Where the targeted path contained a valid workflow JSON file, the file could additionally be loaded and executed, potentially triggering actions on downstream systems connected to that workflow.
The localFile source option is hidden from the n8n UI since v1.2 but remains accessible via the REST API.
Patches
The issue has been fixed in n8n version 2.20.0 or 2.19.3. Users should upgrade to this version or later to remediate the vulnerability.
Workarounds
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
- Restrict workflow creation and editing permissions to fully trusted users only.
- Restrict network access to the n8n REST API to 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 2.19.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2vx9-7wpg-88jq 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-2vx9-7wpg-88jq 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-2vx9-7wpg-88jq. 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-2vx9-7wpg-88jq in your dependencies?
O3 detects GHSA-2vx9-7wpg-88jq across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
