What is CVE-2025-7395?

A certificate verification error in wolfSSL can compromise the verification of server certificate domain names when configurations include WOLFSSL_SYS_CA_CERTS and WOLFSSL_APPLE_NATIVE_CERT_VALIDATION. This vulnerability allows any valid certificate issued by a trusted Certificate Authority (CA) to be accepted by the client application, irrespective of whether the hostname matches. This oversight creates potential security risks, enabling man-in-the-middle attacks or unauthorized access.
