Technical description

n8n before 2.42.6, 2.43.x before 2.43.3, and 3.x before 3.0.1 contains a remote code execution vulnerability via deprecated Function, Function Item, and LangChain Code nodes running outside task runner isolation. Authenticated users who can create, modify, or import workflows naming these hidden node types can execute JavaScript in the n8n main process.

CVE-2026-115517—

37.2%

——11Unrestricted network access between execution contexts in KNIME Business Hub before version 1.19.0 allows an authenticated remote user to access open network ports on executors in different execution contexts. This only poses a security issue if the IP address of the attacked executor is know and there are open network ports that provided access without further authentication. By default no network ports are open. However, depending on the running workflows, ports may be opened and provide an attack surface. As a workaround, network policies can be created manually.7d CVE-2026-1140878.1 HIG

——13Trigger.dev before 4.5.6 self-hosted Docker Compose deployments using the default secrets from hosting/docker/.env.example allow authentication bypass because the hardcoded MAGIC_LINK_SECRET lets anyone forge valid magic link tokens. Unauthenticated attackers can log in as any email address, then reach Postgres, Redis, and ClickHouse with default credentials from runner containers on infrastructure networks, compromising all tenant data.10d CVE-2026-1094438.8 HIG

——18JoySafeter through 1.0.0 contains a remote code execution vulnerability that allows authenticated users to run operating system commands via an unsandboxed execute tool in Copilot standard mode. Attackers can self-register, select standard mode in the WebSocket chat.start extension, and have the agent invoke subprocess.run with shell=True on the host to access other tenants' data and server secrets.10d CVE-2026-1094415.8 MED

——12LangAlpha through 2026.09.07 contains an improper isolation vulnerability that places all tenants' sandbox containers on Docker's shared default bridge network with inter-container communication enabled. Authenticated users with code execution in their own sandbox can connect directly to other tenants' containers, bypassing require_workspace_owner checks to read files such as vault secrets from exposed servers.10d CVE-2026-34009—

——0An improper isolation or compartmentalization vulnerability has been reported to affect Notes Station 3. If a local attacker gains an administrator account, they can then exploit the vulnerability to compromise the security of the system. We have already fixed the vulnerability in the following version: Notes Station 3 3.9.11 and later15d CVE-2026-1082639.9 CRI

——11Astron Agent is an agentic workflow platform for building and running AI agents. Prior to 1.1.2, the default workflow code-node path through /console-api/workflow/code/run and /workflow/v1/run selects LocalExecutor in core/workflow/engine/nodes/code/code_node.py when CODE_EXEC_TYPE is not explicitly changed. LocalExecutor supplies complete Python builtins to dynamic code execution without the documented sandbox restrictions. An authenticated low-privilege tenant can execute code as root in the core-workflow container and use shared service and database credentials to bypass application-level tenant checks, read or modify other tenants' data, and disrupt shared services. This issue is fixed in version 1.1.2.14d
