There is no fixed version for Centos:7 flatpak-builder.

NVD Description

Note: Versions mentioned in the description apply only to the upstream flatpak-builder package and not the flatpak-builder package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Flatpak passes through arbitrary vendor-extension keys unmodified when exporting an application's Desktop Entry (.desktop) and D-Bus Service (.service) files, instead of validating against an allowlist. A malicious Flatpak app can use this to cause denial of service (e.g. forced application restart loops) or to influence host D-Bus/systemd activation behavior beyond what the sandbox is intended to permit.
