CVE ID         : CVE-2019-18978

This package allowed ../ directory traversal to access private
resources because resource matching did not ensure that
pathnames were in a canonical format.

For Debian 9 stretch, this problem has been fixed in version
0.4.0-1+deb9u2.

We recommend that you upgrade your ruby-rack-cors packages.
