The file version.php
https://github.com/ZerooCool/phpsecinfo/blob/phpsecinfo-zeroocool-v0.2.1/20070406-phpsecinfo-v0.2.1/PhpSecInfo/Test/Core/version.php

I don't really understand the use of this new test and hardcoding the version information.
This test already checks for the latest version

And if you dislike deserializing data, you could also simply use https://www.php.net/releases/?json=1&version=7

BTW: We can ping external URLs only if \Piwik\SettingsPiwik::isInternetEnabled() is enabled

Then use relative link ?
