      "value": "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.\""

      "value": "Se ha identificado una debilidad en zhayujie chatgpt-on-wechat CowAgent 2.1.0. Este problema afecta la función verify_server del archivo channel/wechatmp/common.py del componente wx Endpoint. Esta manipulación del argumento wechatmp_token causa falta de autenticación. El ataque puede iniciarse de forma remota. El exploit se ha puesto a disposición del público y podría usarse para ataques. La actualización a la versión 2.1.1 es capaz de abordar este problema. Nombre del parche: 3d7c68bac6ee74fad63f43cf99e45c62e202ed55. Se sugiere actualizar el componente afectado. El proyecto confirma: ’Hemos añadido una comprobación explícita de no vacío para wechatmp_token en verify_server() para que el endpoint /wx ahora falle cerrado con 403 Forbidden siempre que el token falte o se deje con el valor vacío predeterminado, en lugar de depender de una comprobación de firma que degenera silenciosamente en un hash predecible.’"
