CVE-2026-25049

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.

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.

### Impact Additional exploits in the expression evaluation of n8n have been identified and patched following [CVE-2025-68613](https://github.com/n8n-io/n8n/security/advisories/GHSA-v98v-ff95-f3cp). 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. ### Patches The issue has been fixed in n8n versions 1.123.17 and 2.5.2. Users should upgrade to 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. - Deploy n8n in a hardened environment with restricted operating system privileges and network access to reduce the impact of potential exploitation. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures. ### Resources - Best practices for [securing n8n](https://docs.n8n.io/hosting/securing/overview/) - Initial vulnerability advisory: [CVE-2025-68613](https://github.com/n8n-io/n8n/security/advisories/GHSA-v98v-ff95-f3cp) --- n8n has adopted CVSS 4.0 as primary score for all security advisories. CVSS 3.1 vector strings are provided for backward compatibility. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

n8n es una plataforma de automatización de flujos de trabajo de código abierto. Antes de las versiones 1.123.17 y 2.5.2, un usuario autenticado con permiso para crear o modificar flujos de trabajo podría abusar de expresiones manipuladas en los parámetros del flujo de trabajo para desencadenar la ejecución no intencionada de comandos del sistema en el host que ejecuta n8n. Este problema ha sido parcheado en las versiones 1.123.17 y 2.5.2.
