GHSA-f2cp-m7mv-8jpv
GHSA-f2cp-m7mv-8jpv is a Path Traversal vulnerability in n8n. O3 Security confirms whether GHSA-f2cp-m7mv-8jpv is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

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 Elasticsearch and ElasticSecurity nodes built REST endpoints by interpolating user-provided identifiers straight into the request path. A value containing path separators or dot segments changed which endpoint the request actually reached, so an operation intended for one document could hit another index or a cluster administration endpoint instead, under the stored Elasticsearch credential. The patch encodes each identifier as a single URL path segment and rejects values that normalise away.
Patches
The issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. 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:
- Restrict n8n instance access to fully trusted users only.
- Disable the affected nodes by adding
n8n-nodes-base.elasticsearchandn8n-nodes-base.elasticSecurityto theNODES_EXCLUDEenvironment variable if they are not required. - Audit existing workflows that use these nodes and ensure that index and document identifier fields do not accept externally-controlled input.
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 1.123.76 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f2cp-m7mv-8jpv 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-f2cp-m7mv-8jpv 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-f2cp-m7mv-8jpv. 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-f2cp-m7mv-8jpv in your dependencies?
O3 detects GHSA-f2cp-m7mv-8jpv across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
