Summary
OpenSSL pinning bypass
Details

When CURLOPT_PINNEDPUBLICKEY is configured alongside options that disable standard peer verification (CURLOPT_SSL_VERIFYPEER = 0 and CURLOPT_SSL_VERIFYHOST = 0), libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check under these disabled-verification conditions allows unauthenticated connections to succeed when they should be rejected.
