Description
n8n before 1.123.83, 2.x before 2.41.4, and 2.42.x before 2.42.1 contains a code execution vulnerability in the Git node Log operation, which fails to strip a repository's local git configuration before invoking an external program. Authenticated members who can point the node, including as an agent tool, at a repository whose local configuration they control can execute programs as the n8n process user.
