CVE-2026-65598

n8n before 1.123.64 Remote Code Execution via Git Clone

State: Published
Severity: 8.9 High

Description

n8n before 1.123.64, 2.29.8, and 2.30.1 contains a TOCTOU race condition in the Git node's clone operation that allows authenticated users to bypass path restrictions by swapping a directory for a symlink after the path is validated but before the clone runs. This lets an attacker plant a crafted repository in the community node directory, which n8n loads as a custom node on the next restart, executing arbitrary JavaScript on the server. Both self-hosted and cloud instances are affected.
