Arbitrary File Read via Argument Injection in n8n Git Node
CVE-2026-44790 is a critical argument injection vulnerability in the n8n Git node, specifically during Git Push operations. According to the provided context, an authenticated but low-privileged user with permission to create or modify workflows can inject malicious command-line flags into the Git invocation. This improper neutralization of argument delimiters or options allows attacker-controlled CLI parameters to be passed to the underlying Git command, resulting in arbitrary file read from the n8n server. Exposed files may include configuration files, credentials, and environment-variable data. The issue affects n8n versions below 1.123.43, 2.20.7, and 2.22.1.
