CVE-2026-123791 Details
Description
A vulnerability was detected in OpenBMB Internet of Agents up to 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. This affects the function _primary_field_query of the file common/utils/milvus_utils.py of the component Agent Registry. The manipulation of the argument key results in improper neutralization of special elements in data query logic. The attack may be launched remotely. The exploit is now public and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The project was informed of the problem early through an issue report but has not responded yet.
An expression injection vulnerability has been identified in OpenBMB Internet of Agents versions prior to commit 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. The issue arises in the Agent Registry component, specifically within the '_primary_field_query' function of 'common/utils/milvus_utils.py'. The vulnerability allows for improper neutralization of special characters in data query logic, which can be exploited remotely. The application follows a rolling release model, so no specific version details are available for affected or updated releases.
It is recommended to validate agent names at the API layer, ensuring they conform to a specified character set before storage or query. Additionally, double quotes and backslashes should be escaped in query expressions, or a parameterized query interface should be used. Finally, existence checks and write results should be verified explicitly, rather than allowing failures to be swallowed.
