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

high Nessus Plugin ID 298981

Synopsis

The n8n Node.js Package installed on the remote host is affected by an information disclosure vulnerability.

Description

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 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), resulting in potential information disclosure.
(CVE-2025-61917)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to n8n Node.js Package version 1.114.3 or later.
