A 3rd party development library including with Drupal 8 development dependencies is vulnerable to remote code execution. This is mitigated by the default .htaccess protection against PHP execution, and the fact that Composer development dependencies aren't normal installed.

To be sure you aren't vulnerable, you can remove the <siteroot>/vendor/phpunit directory from your production deployments
