SCA: security update for n8n (GHSA-f77h-j2v7-g6mw)

medium Tenable Cloud Security Plugin ID 440998

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 versions 1.123.32, 2.17.4, and 2.18.1, the
/chat WebSocket endpoint used by the Chat Trigger node's Hosted Chat feature did not verify that an
incoming connection was authorized to interact with the target execution. An unauthenticated remote
attacker who could identify a valid execution ID for a workflow in a waiting state could attach to that
execution, receive the pending prompt intended for the legitimate user, and submit arbitrary input to
resume or influence downstream workflow behavior. This issue has been patched in versions 1.123.32,
2.17.4, and 2.18.1. (CVE-2026-42228)

Solution

Update the n8n library and its related packages to version 1.123.32 or later.
