(PHPUnit: Remote code execution)

    When PHPUnit is installed in a production environment via composer and
      these modules are in a web accessible directory, the eval-stdin.php file
      in PHPUnit contains vulnerable statements that trigger the vulnerability.
  
Impact :

    A remote attacker could possibly execute arbitrary PHP code or cause a
      Denial of Service condition.
  
Workaround :

    There are several ways to fix or mitigate this vulnerability:
    Remove PHPUnit from the production environment.
    Update PHPUnit.
    Manually apply the patch.
    Disable direct access to the composer packages by placing .htaccess file
      to /vendor folder.");
