Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Unauthenticated proxy and agent communication can allow unauthorized access to peer pod VMs. Securing the transport layer via automatically-negotiated mutual TLS (mTLS) is critical to prevent malicious interception and manipulation.
Privilege Escalation: Allowing dynamic VM guest agent reconfiguration via untrusted or unmeasured cloud-init userdata allows attackers who control pod specs or metadata to execute arbitrary configuration adjustments inside the trusted VM.
Injection: Unsanitized Kubernetes metadata elements (like pod names or namespaces) used directly to construct hypervisor virtual machine names allow injection attacks across vSphere, Azure, AWS, and libvirt.
