Check your server’s composer files for known PHP vulnerabilities

The Sensio people have made so cool stuff including the SensioLabs Security Checker. You can use it via composer but you can also download a PHAR file and scan your entire server.

wget -O ~/security-checker.phar
find /var/www -type f -name "composer.lock" -exec php ~/security-checker.phar security:check {} ;
