n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a remote code execution vulnerability in the Git node. Authenticated users with rights to create and execute workflows can stage a crafted local repository that causes git to run hooks under default git security settings, executing arbitrary commands as the n8n process user. Both self-hosted and cloud instances are affected.
AnalysisAI
Remote code execution in n8n's Git node allows authenticated users with workflow creation and execution rights to run arbitrary OS commands as the n8n process user by staging a crafted repository that triggers git hook execution under default git security settings. All 1.x versions before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 are affected across both self-hosted and cloud deployments. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid n8n account with workflow creation and execution permissions (authenticated, low-privilege). … 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:H/VI:H/VA:H) is well-calibrated to the actual risk: network-accessible, low complexity, no specific attack prerequisites, requiring only a low-privileged authenticated account. … 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 | Upgrade to a patched release immediately: n8n 1.123.67 for all 1.x deployments, 2.31.5 for 2.x deployments below 2.32, or 2.32.1 for 2.32.x deployments. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all n8n deployments currently running affected versions (1.x < 1.123.67, 2.x < 2.31.5, 2.32.x < 2.32.1) and determine whether untrusted users possess workflow creation or execution rights. …
