UPDATE: The instructions here are no longer necessary! Resizing the disk image is now possible right from the UI since Docker for Mac Version 17.12.0-ce-mac49 (21995).
If you are getting the error: No space left on device
Configuring the qcow2 size cap is possible in the current versions:
# my disk is currently 64GiB
Prior to Drupal 8, we relied on manual escaping variables by our developers and themers. Every variable was either run through check_plain(), filter_xss() or another filter function manually or it was assumed to be safe. You can see where this assumption can easily be overlooked/forgotten and we end up with a security vulnerability usually in the form of an XSS attack.
One of the major decisions for choosing Twig in Drupal 8 was due to its autoescape security feature which all variables can be escaped automatically while they are printed. This alleviates a bunch of concerns and burden on the Security Team as well as protect Drupal Sites by default. This is equivalent to Drupal 7 writing <?php print check_plain($variable); ?> on each variable printed.
