Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname.
The product initializes or sets a resource with a default that is intended to be changed by the product’s installer, administrator, or maintainer, but the default is not secure.
