Summary
n8n has an Authentication Bypass in its Chat Trigger Node
Details

Impact

When the Chat Trigger node is configured with n8n User Auth authentication, the authentication check could be circumvented. - This issue requires the Chat Trigger node to be configured with n8n User Auth authentication (non-default).

Patches

The issue has been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. 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: - Limit workflow creation and editing permissions to fully trusted users only. - Use a different authentication method for the Chat Trigger node, or restrict network access to the webhook endpoint to trusted origins.

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