In Mitre's CVE dictionary: CVE-2022-47951.
More information:

An issue was discovered in Glance, OpenStack Image Registry and Delivery Service - Daemons. 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 2:17.0.0-5+deb10u1.

We recommend that you upgrade your glance packages.
