SCA: security update for n8n (GHSA-6xcw-7xm6-48c6)

high Tenable Cloud Security Plugin ID 447937

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the legacy
expression engine generated source text by calling the mutable global JSON.stringify while printing
synthetic string literals and interpolating timezone data. An expression could replace JSON.stringify and
cause later generated source to contain executable attacker-controlled code. The affected code-generation
paths include packages/@n8n/expression-runtime/src/bridge/isolated-vm-bridge.ts and
packages/@n8n/tournament/src/ExpressionBuilder.ts, and the issue does not affect the vm expression engine.
This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2. (CVE-2026-86083)

Solution

Update the n8n library and its related packages to version 1.123.76 or later.
