CVE-2026-27495

n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could exploit a vulnerability in the JavaScript Task Runner sandbox to execute arbitrary code outside the sandbox boundary. On...

CVE-2026-27495

CVE-2026-27495 affects n8n, an open-source workflow automation platform. Before versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could exploit a vulnerability in the JavaScript Task Runner sandbox to execute arbitrary code outside the sandb...

n8n has a Sandbox Escape in its JavaScript Task Runner

Impact An authenticated user with permission to create or modify workflows could exploit a vulnerability in the JavaScript Task Runner sandbox to execute arbitrary code outside the sandbox boundary. On instances using internal Task Runners default runner mode, this could result in full compromise...

Arbitrary Code Injection

Overview Affected versions of this package are vulnerable to Arbitrary Code Injection. An attacker can execute arbitrary code outside the intended sandbox boundary by creating or modifying workflows after authenticating with sufficient permissions. Workaround This vulnerability can be mitigated b...

n8n Node.js Package >= 1.65.0 < 1.114.3 Unsafe Buffer Allocation Memory Disclosure (CVE-2025-61917)

The version of the n8n Node.js Package installed on the remote host is = 1.65.0 and prior to 1.114.3. It is, therefore, affected by an information disclosure vulnerability: - The use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allows untrusted code to allocate uninitialize...

CVE-2025-61917

n8n is an open source workflow automation platform. From version 1.65.0 to before 1.114.3, the use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the sa...

n8n's Unsafe Buffer Allocation Allows In-Process Memory Disclosure in Task Runner

Impact The use of Buffer.allocUnsafe and Buffer.allocUnsafeSlow in the task runner allowed untrusted code to allocate uninitialized memory. Such uninitialized buffers could contain residual data from within the same Node.js process for example, data from prior requests, tasks, secrets, or tokens,...
