MSA-17-0020: Admins may not know that exposing vendor directory is a security risk

by Marina Glancy.  

Directories vendor/ and node_modules/ that are created by composer and used during Moodle development may expose dangerous scripts to the web and should never be present on production sites. This issue adds a respective security check.

Manual action may be required from the site admin to remove composer-generated directories or prevent access to them from the web.
