Descriptions

In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sig_algo field differs between the certificate_verify message and the certificate message.

En wolfSSL versiones anteriores a 5.2.0, una comprobación del certificado puede ser omitida durante el intento de autenticación por parte de un cliente TLS versión 1.3 a un servidor TLS versión 1.3. Esto ocurre cuando el campo sig_algo difiere entre el mensaje certificate_verify y el mensaje de certificado
