NewCVE-2026-56775 (opens in a new tab)How to fix?
Upgrade n8n to version 1.123.55, 2.25.7, 2.26.2 or higher.
Overview
n8n is a n8n Workflow Automation Tool
Affected versions of this package are vulnerable to Incorrect Authorization in the evaluation test runs controller, where three state-changing endpoints authorize actions against the workflow:read permission instead of the action-appropriate workflow:execute scope. A user with the read-only project:viewer role can start new evaluation test runs, cancel in-flight runs, or delete run records on workflows they only have read access to by calling those endpoints. Exploitation affects only instances with Advanced Permissions (Enterprise or Cloud) where projects and viewer roles are in use.
