CVE-2026-123032 Details
Description
A security flaw has been discovered in OpenBMB Internet of Agents up to 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. This affects the function ConnectionManager.connect of the file im_server/app.py of the component WebSocket Connection Manager. The manipulation of the argument agent_name results in missing authentication. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.
An authentication bypass vulnerability has been identified in OpenBMB Internet of Agents versions prior to commit 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. The issue arises in the WebSocket Connection Manager, specifically within the ConnectionManager.connect function in im_server/app.py. The vulnerability allows for remote exploitation by manipulating the agent_name argument, leading to unauthorized access and control over WebSocket connections.
It is recommended to implement identity verification during the WebSocket handshake by issuing a random token at registration and validating it before accepting the connection. Additionally, the WebSocket connection manager should reject connections that use an agent name already in use or close the existing connection before accepting the new one.
