Package        : ruby-rack-cors
Version        : 0.2.9-1+deb8u1
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 8 "Jessie", this problem has been fixed in version
0.2.9-1+deb8u1.

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