curl: mbedTLS / wolfSSL / rustls backends silently skip hostname verification when CURLOPT_SSL_VERIFYPEER=0

Summary When an application sets CURLOPTSSLVERIFYPEER=0 while keeping CURLOPTSSLVERIFYHOST=2 the default, the mbedTLS, wolfSSL, and rustls TLS backends silently skip the hostname-vs-certificate check. The OpenSSL, GnuTLS, and Schannel backends correctly preserve hostname checking under the same...

Hi all, When the rustls backend is configured to use the OS native CA store --ca-native / CURLSSLOPTNATIVECA, any CRL file supplied via --crlfile / CURLOPTCRLFILE is silently ignored. The option is accepted — CURLEOK from curleasysetopt, exit 0 from the command line — and revoked certificates pas...
