n8n is an open source workflow automation platform. Prior to versions 1.123.17 and 2.5.2, an authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n. This issue has been patched in versions 1.123.17 and 2.5.2.
AnalysisAI
n8n workflow automation platform has an authenticated code execution vulnerability (CVSS 9.9) through improper runtime behavior modification, enabling server takeover.
Technical ContextAI
n8n < 1.123.17 / 2.5.2 has a CWE-913 improper control of dynamically-managed code resources that allows authenticated users to modify runtime behavior and execute arbitrary code on the server.
