Source agreement

Tam uyum

Evidence confidence

%63

Short explanation

A code execution vulnerability in n8n stems from the Git node Log operation failing to strip local git configuration before invoking an external program, allowing authenticated users to execute programs by pointing to a controlled repository.

Why does it matter?

It allows authorized users to execute external programs with the privileges of the n8n process user, posing a high risk to system confidentiality and integrity.

What should be done?

  • Follow vendor security advisories
  • Upgrade to unaffected versions

Show the technical text from the sources

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.
