How to fix?

Upgrade Centos:8 osbuild-composer-core to version 0:101-1.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream osbuild-composer-core package and not the osbuild-composer-core package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

A flaw was found in osbuild-composer. A condition can be triggered that disables GPG verification for package repositories, which can expose the build phase to a Man-in-the-Middle attack, allowing untrusted code to be installed into an image being built.
