CVE-2026-123963 Details
Description
A security vulnerability has been detected in OpenBMB Internet of Agents up to 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. The impacted element is the function register of the file im_server/app.py of the component Agent Registry. Such manipulation of the argument desc/name leads to missing authentication. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.
A vulnerability allowing for unauthenticated registrations has been identified in OpenBMB Internet of Agents versions prior to commit 9d78e88e47160eb42ee1ee8538c05e1c2c47877a. The issue resides in the Agent Registry component, specifically within the register function of im_server/app.py. The vulnerability allows remote attackers to register an unlimited number of agents by exploiting the lack of input validation and authentication on the 'name' and 'desc' fields. This flaw can lead to a denial-of-service condition and manipulation of the agent retrieval system.
It is recommended to implement authentication requirements for the '/register' endpoint, along with rate limits and quotas. Additionally, the API should validate 'name' and 'desc' inputs before processing them, and the agent retrieval system should be adjusted to prevent newly registered entries from dominating recall.
