GHSA-jh8h-6c9q-7gmw: n8n has an Authentication Bypass in its Chat Trigger Node
Summary
n8n, a workflow automation tool, has a security flaw in its Chat Trigger node where authentication (the process of verifying a user's identity) can be bypassed when configured with n8n User Auth. This only affects users who have specifically set up this non-default authentication method on their Chat Trigger node.
Solution / Mitigation
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. If upgrading is not immediately possible, administrators can temporarily: 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 (the URL that receives Chat Trigger requests) to trusted origins. These workarounds do not fully remediate the risk and should only be used as short-term measures.
