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."
