VM images built with Image Builder and Proxmox provider use default credentials in github.com/kubernetes-sigs/image-builder
Description: A critical security vulnerability has been identified in Kubernetes Image Builder versions ≤ v0.1.37, where default credentials remain enabled during the image build process. Virtual machine images created using the Proxmox provider are particularly affected, as these default credentials are not disabled. Consequently, nodes utilizing these images may be accessible via these default credentials, potentially allowing unauthorized root access. Only Kubernetes clusters with nodes that employ VM images generated via the Image Builder project with the Proxmox provider are impacted.
