An issue was discovered in OpenStack Cinder, a Block Storage service
for OpenStack. By supplying a specially created VMDK flat image that
references a specific backing file path, an authenticated user may
convince systems to return a copy of that file's contents from the
server, resulting in unauthorized access to potentially sensitive data.

For Debian 10 buster, this problem has been fixed in version

We recommend that you upgrade your cinder packages.
