CVE-2026-77084Network attack vector

Code execution via unchecked repository-local Git configuration

Published Aug 20, 2026 · Updated Aug 25, 2026

OS command injection in n8n's Git node allows remote authenticated users to execute code as the n8n process user. The Git node passes certain values from a repository's local Git configuration into Git operations without neutralizing command syntax. Exploitation requires low-privileged authenticated access, a separate file-write flaw to plant the value, and a later Git node operation.
