CVE-2026-77084: n8n before 1.123.69 Remote Code Execution via Git Node Configuration Values
n8n before 1.123.69 (and 2.x before 2.33.4 / 2.34.1) contains a code execution vulnerability in the Git node. The Git node executed certain repository-local git configuration values without neutralizing them, so any subsequent Git node operation against a repository containing a malicious value would execute it as the n8n process user. This is not reachable through the Git node's own configuration controls and requires a separate file-write vulnerability elsewhere to plant the malicious value.

Event History
Frequently Asked Questions
What conditions are required for exploitation?
An attacker must first use a separate file-write vulnerability to place a malicious repository-local Git configuration value in a repository. A subsequent Git node operation against that repository then executes the value as the n8n process user.
Is this reachable through normal Git node configuration?
No. The vulnerable repository-local Git configuration values cannot be set through the Git node's own configuration controls.
Which deployments need remediation?
Deployments running n8n versions before 1.123.69, or 2.x versions before 2.33.4 or 2.34.1, are affected when Git node operations are performed on a repository where a malicious local Git configuration value has been planted.
