wolfSSL Python library `CERT_REQUIRED` mode fails to enforce client certificate requirement

A vulnerability in the handling of verify_mode = CERT_REQUIRED in the wolfssl Python package (wolfssl-py) causes client certificate requirements to not be fully enforced.  Because the WOLFSSL_VERIFY_FAIL_IF_NO_PEER_CERT flag was not included, the behavior effectively matched CERT_OPTIONAL: a peer certificate was verified if presented, but connections were incorrectly authenticated when no client certificate was provided.  This results in improper authentication, allowing attackers to bypass mutual TLS (mTLS) client authentication by omitting a client certificate during the TLS handshake.  The issue affects versions up to and including 5.8.2.

关键功能的认证机制缺失

wolfssl-py 安全漏洞

wolfssl-py是wolfSSL开源的一个Python打包工具。 wolfssl-py 5.8.2及之前版本存在安全漏洞，该漏洞源于未完全强制执行客户端证书要求，可能导致身份验证不当和绕过相互TLS客户端身份验证。
