Sources and claim methodology

Upstream source description

A flaw was found in quay-builder-qemu. A remote attacker could exploit this by compromising the upstream `Noelware/docker-manifest-action` used in the release workflow, which is pinned to a mutable branch. This allows the attacker to inject arbitrary code, leading to the exfiltration of sensitive registry credentials or the publication of malicious images. The workflow also exposes the default GitHub token, increasing the severity of the compromise.
