Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Flaws in TPM attestation and metadata validation allowed nodes to bypass identity verification, relying on unverified common names or incorrect zone handling rather than secure cryptographic proofs.

Auth Bypass: Deriving VM identity from user-supplied DNS SANs instead of the authenticated Username allowed malicious actors to perform node identity spoofing.

Broken Authentication: Missing validation of TPM Endorsement Key (EK) certificates and CRL checks against a trusted root CA allowed unauthenticated nodes to pass attestation.
