CVE-2026-6126 Details
Description
A weakness has been identified in zhayujie chatgpt-on-wechat CowAgent 2.0.4. The affected element is an unknown function of the component Administrative HTTP Endpoint. This manipulation causes missing authentication. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A critical vulnerability has been identified in zhayujie chatgpt-on-wechat CowAgent version 2.0.4 and earlier. The issue arises from the Administrative HTTP Endpoint, which lacks authentication, allowing unauthenticated remote attackers to access and manipulate sensitive application data. Exploitation of this vulnerability could lead to unauthorized access to API keys, modification of application configuration, interception of user conversations, and unauthorized access to application logs and memory content.
To address this vulnerability, it is recommended to implement authentication middleware for all Web Console endpoints, bind the application to localhost by default instead of '0.0.0.0', add CSRF protection for state-changing endpoints, and implement rate limiting to prevent brute-force attacks.
