SCA: security update for n8n (GHSA-35jj-42hp-8gmq)

medium Tenable Self-Hosted Container Security Plugin ID 447931

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 2.37.7 and 2.38.2, the /chat WebSocket route
 accepted a resumeToken and resumed a paused execution without checking that the target node supported chat
 messages. An anonymous form submitter who received that token could reuse it on the chat route to release
 a Send-and-Wait, non-chat HITL, or Wait approval gate. The affected authorization logic is
 packages/cli/src/chat/chat-execution-manager.ts, where canResumeOverChat did not gate the resume target.
 This issue is fixed in versions 2.37.7 and 2.38.2. (CVE-2026-86077)

Solution

Update the n8n library and its related packages to version 2.37.7 or later.
