SCA: security update for n8n (GHSA-43v7-fp2v-68f6)

medium Tenable Self-Hosted Container Security Plugin ID 439215

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- n8n is an open source workflow automation platform. Prior to version 2.5.0, when the Source Control
feature is configured to use SSH, the SSH command used for git operations explicitly disabled host key
verification. A network attacker positioned between the n8n instance and the remote Git server could
intercept the connection and present a fraudulent host key, potentially injecting malicious content into
workflows or intercepting repository data. This issue only affects instances where the Source Control
feature has been explicitly enabled and configured to use SSH (non-default). The issue has been fixed in
n8n version 2.5.0. Users should upgrade to this version or later to remediate the vulnerability. If
upgrading is not immediately possible, administrators should consider the following temporary mitigations:
Disable the Source Control feature if it is not actively required, and/or restrict network access to
ensure the n8n instance communicates with the Git server only over trusted, controlled network paths.
These workarounds do not fully remediate the risk and should only be used as short-term mitigation
measures. (CVE-2026-33724)

Solution

Update the n8n library and its related packages to version 2.5.0 or later.
