GHSA-gf29-4f56-r2jf n8n: Git Node fetch/pull/pushTags Operations Bypass Sandbox Path Restriction

• npm n8n: < 1.123.67 → fixed in 1.123.67 • npm n8n: >= 2.32.0, < 2.32.1 → fixed in 2.32.1 • npm n8n: >= 2.0.0-rc.0, < 2.31.5 → fixed in 2.31.5

Impact Authenticated n8n users with workflow create/execute rights could use the Git node's fetch, pull, or push-tags operations to bypass the repository-path containment checks that already protected clone and push. By pointing an allowlisted remote configuration value at a local path outside the intended sandbox, an attacker could pull an arbitrary local git repository into the workspace and subsequently read its files and history. Patches The issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability. Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: • Restrict n8n instance access to fully trusted users only. • Disable the Git node by adding `n8n-nodes-base.git` to the `NODES_EXCLUDE` environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
