n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node validated the repository parameter for fetch or pull, but setUpstream wrote a branch..remote value into repository configuration without validating it. A later fetch or pull resolved the remote from that configuration instead of the checked parameter. An authenticated workflow editor could therefore point Git at any local repository readable by the n8n process and receive its contents through packages/nodes-base/nodes/Git/GenericFunctions.ts. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.

GHSA-qgpw-8g46-w95v — n8n: Git Node branch..remote Config Key Bypasses Sandbox Path Restriction, Enabling Local Git Repository Read

Affected: npm: n8n

## Impact

The Git node validated the repository that a fetch or pull targeted, but `setUpstream` wrote a `branch.<name>.remote` value into the repository's own configuration without validating it. A subsequent fetch or pull resolved the remote from that configuration rather than from the checked parameter, so an authenticated user with workflow-edit permission could point it at any local repository the n8n process could read and receive its contents. The patch validates the branch remote configuration on the same terms as the repository parameter.

## Patches

The issue has been fixed in n8n versions 1.123.76, 2.37.7, and 2.38.2. 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. - Ensure the n8n process runs under a dedicated low-privilege OS user account to limit the scope of any filesystem access.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
