Lifecycle Timeline
3DescriptionCVE.org
n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node validated the repository parameter for fetch or pull, but setUpstream wrote a branch..remote value into repository configuration without validating it. A later fetch or pull resolved the remote from that configuration instead of the checked parameter. An authenticated workflow editor could therefore point Git at any local repository readable by the n8n process and receive its contents through packages/nodes-base/nodes/Git/GenericFunctions.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
AnalysisAI
Path traversal in n8n's Git node allows authenticated workflow editors to exfiltrate the contents of arbitrary local git repositories readable by the n8n process. The flaw exists in packages/nodes-base/nodes/Git/GenericFunctions.ts: setUpstream writes an unvalidated branch.<branch>.remote value into the repository configuration, and a subsequent fetch or pull resolves the remote from that persisted config rather than the validated repository parameter - a TOCTOU-style validation bypass classified as CWE-22. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated n8n user account with workflow editing permissions - on many self-hosted n8n instances, all authenticated users hold this role by default. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L) scores 5.3, reflecting a medium-severity, network-accessible flaw with no complexity barriers but requiring low-privilege authentication. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patches are available: upgrade n8n to version 1.123.76 (1.x branch), 2.37.7 (2.x branch), or 2.38.2 (2.38.x branch) following the standard n8n upgrade procedure. … Detailed patch versions, workarounds, and compensating controls in full report. |
