Name of the Vulnerable Software and Affected Versions google-checkout-php-sample-code versions prior to 1.3.2

Description The issue arises from the failure to verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate. This allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

Recommendations For versions prior to 1.3.2, update to version 1.3.2 or later to resolve the issue. As a temporary workaround, consider implementing certificate validation to ensure the server hostname matches the domain name in the certificate.
