CVE-2026-123675OpenBMB Internet of Agents code injection

High priorityMedium5.5EPSS not scored yet

CVE-2026-123675 is a code injection in OpenBMB Internet of Agents, rated medium (5.5 on CVSS 4.0).

Why this priority: A public proof of concept exists and exploitation can be automated.

Published · Updated · NVD status: Deferred

What it is

Input is evaluated as code by the application, so an attacker's code runs inside it. Input is passed to another component as instructions rather than data.

How it is reached

An attacker can exploit it over the network, without an account, and nobody has to click anything.

What an attacker gains

The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker run commands or code with the privileges of the affected service. The damage can spread past the vulnerable component into others.

Is it being exploited?

CISA's SSVC assessment notes a public proof of concept. It can be exploited automatically, at scale.

What to do

  1. No fixed version is listed yet. Find every place OpenBMB Internet of Agents runs, watch the references for a fix, and plan a replacement if it is no longer supported.
  2. While there is no fix, keep it off the internet or behind a VPN, allowlist or authenticating proxy.

Description from NVD

A flaw has been found in OpenBMB Internet of Agents up to 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. This affects the function execute_code of the file im_client/agents/tools/code_executor.py of the component Code Executor Tool. This manipulation of the argument filename/lang causes code injection. The attack can be initiated remotely. The exploit has been published and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.

What this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

  • Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
  • Template engines. The flaw sits between untrusted input and code or command execution.

Trust boundaries in play

  • Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
  • Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
  • Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.

Questions to answer about your own systems

  • Where does OpenBMB Internet of Agents run in your systems, and at which version?
  • Which of those instances can be reached from the internet or partner networks?
  • What can it reach once compromised: which data stores, secrets and services?
