  "title": "OpenSSL pinning bypass",
  "description": "When \u0060CURLOPT_PINNEDPUBLICKEY\u0060 is configured alongside options that disable standard peer verification (\u0060CURLOPT_SSL_VERIFYPEER = 0\u0060 and \u0060CURLOPT_SSL_VERIFYHOST = 0\u0060), 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.",
