medium Tenable Self-Hosted Container Security Plugin ID 447917

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 Instance AI workflow
summary used node names and connection keys from stored workflows as ordinary object keys. A workflow
submitted through the REST API could contain __proto__ or constructor, causing nested writes to reach
Object.prototype in the main n8n process and disrupt later requests. The affected function is
summarizeWorkflowStructure in packages/@n8n/instance-ai/src/tools/workflows/summarize-workflow.ts. This
issue is fixed in versions 2.37.7 and 2.38.2. (CVE-2026-86078)

Solution

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