Summary

A missing authentication vulnerability was found in the wx Endpoint component of zhayujie chatgpt-on-wechat CowAgent 2.1.0, specifically in the verify_server function of channel/wechatmp/common.py. The attack can be initiated remotely by manipulating the wechatmp_token argument, and the exploit is publicly available.

Risk Assessment

The organization is at risk of unauthorized access to the /wx endpoint, potentially leading to control over the WeChat integration, data leakage, or privilege escalation.

Recommendation

Immediately upgrade to version 2.1.1, which includes the fix (commit 3d7c68bac6ee74fad63f43cf99e45c62e202ed55) that enforces a non-empty token check and returns 403 Forbidden on missing or empty tokens.

Original NVD description (English source)

A weakness has been identified in zhayujie chatgpt-on-wechat CowAgent 2.1.0. This issue affects the function verify_server of the file channel/wechatmp/common.py of the component wx Endpoint. This manipulation of the argument wechatmp_token causes missing authentication. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.1.1 is capable of addressing this issue. Patch name: 3d7c68bac6ee74fad63f43cf99e45c62e202ed55. It is suggested to upgrade the affected component. The project confirms: "We've added an explicit non-empty check for wechatmp_token in verify_server() so that the /wx endpoint now fails closed with 403 Forbidden whenever the token is missing or left at the default empty value, instead of relying on a signature check that silently degenerates to a predictable hash."
