Description
n8n versions before 1.123.67 contain a path traversal vulnerability in the Git node's fetch, pull, and push-tags operations that allows authenticated users to bypass repository-path containment checks. Attackers with workflow create/execute rights can point allowlisted remote configurations at local paths outside the sandbox to pull arbitrary git repositories and read their files and history.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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.
Remediation status
No patched version of the affected component has shipped for CVE-2026-72770 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 CVE-2026-72770 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 CVE-2026-72770. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
