CVE-2026-59209 Details
Description
n8n is an open source workflow automation platform. Prior to 1.123.61, 2.27.4, and, 2.28.1, an authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression and exfiltrate the secret through item data. This issue is fixed in versions 1.123.61, 2.27.4, and 2.28.1.
A vulnerability exists in n8n workflow automation platform versions prior to 1.123.61, 2.27.4, and 2.28.1. An authenticated user with editor access to a shared workflow could access credential-filled headers through the $request object in an HTTP Request node's pagination expression. This secret could then be transferred via item data, exfiltrating it through a subsequent HTTP Request node. The issue affects instances with N8N_EXPRESSION_ENGINE=vm' enabled, where shared credentials are available to non-owner users.
Users should upgrade to n8n versions 1.123.61, 2.27.4, or 2.28.1. If an immediate upgrade is not possible, consider restricting workflow sharing to trusted users and avoiding the use of shared credentials with editor access on untrusted workflows that utilize HTTP Request pagination.
