      "value": "Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, this vulnerability allows remote attackers to bypass authentication on affected installations of FlowiseAI Flowise. Authentication is not required to exploit this vulnerability. The specific flaw exists within the resetPassword method of the AccountService class. There is no check performed to ensure that a password reset token has actually been generated for a user account. By default the value of the reset token stored in a users account is null, or an empty string if they've reset their password before. An attacker with knowledge of the user's email address can submit a request to the \"/api/v1/account/reset-password\" endpoint containing a null or empty string reset token value and reset that user's password to a value of their choosing. This vulnerability is fixed in 3.1.0."

      "value": "Flowise es una interfaz de usuario de arrastrar y soltar para construir un flujo de modelo de lenguaje grande personalizado. Antes de la versión 3.1.0, esta vulnerabilidad permite a atacantes remotos omitir la autenticación en instalaciones afectadas de FlowiseAI Flowise. La autenticación no es necesaria para explotar esta vulnerabilidad. La falla específica existe dentro del método resetPassword de la clase AccountService. No se realiza ninguna verificación para asegurar que se haya generado realmente un token de restablecimiento de contraseña para una cuenta de usuario. Por defecto, el valor del token de restablecimiento almacenado en la cuenta de un usuario es nulo, o una cadena vacía si han restablecido su contraseña anteriormente. Un atacante con conocimiento de la dirección de correo electrónico del usuario puede enviar una solicitud al endpoint ’/api/v1/account/reset-password’ que contenga un valor de token de restablecimiento nulo o una cadena vacía y restablecer la contraseña de ese usuario a un valor de su elección. Esta vulnerabilidad está corregida en la versión 3.1.0."
