CVE-2026-127082 Overview
Huginn before 2026.11.09 contains an information exposure vulnerability in JqAgent that allows authenticated users to read the server process environment because the jq child process inherits it. Attackers who can create, configure or dry-run a JqAgent can supply a filter using env or $ENV to disclose APP_SECRET_TOKEN, database, SMTP and OAuth secrets.

A flaw was found in Goose. When the terminal integration feature is enabled, the application captures shell command history and sends it verbatim without sanitization to configured Large Language Model (LLM) provider endpoints during queries. If a user enters sensitive data—such as API tokens, passwords, or environment variables containing secrets—in the terminal, this unredacted information is transmitted across trust boundaries. This can lead to sensitive information disclosure, exposing confidential credentials to external service providers and logs.
n8n is an open source workflow automation platform. Prior to versions 2.10.1, 2.9.3, and 1.123.22, an authenticated user with permission to create or modify workflows could use the Python Code node to escape the sandbox. The sandbox did not sufficiently restrict access to certain built-in Python objects, allowing an attacker to exfiltrate file contents or achieve RCE. On instances using internal Task Runners (default runner mode), this could result in full compromise of the n8n host. On instances using external Task Runners, the attacker might gain access to or impact other task executed on the Task Runner. Task Runners must be enabled using `N8N_RUNNERS_ENABLED=true`. The issue has been fixed in n8n versions 2.10.1, 2.9.3, and 1.123.22. Users should upgrade to this version or later to remediate the vulnerability. If upgrading is not immediately possible, administrators should consider the following temporary mitigations. Limit workflow creation and editing permissions to fully trusted users only., and/or disable the Code node by adding `n8n-nodes-base.code` to the `NODES_EXCLUDE` environment variable. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
