          "details": "This flaw is limited to environments actively using the Keylime verifier and requires the ability to submit/manipulate TPM quotes within the attestation workflow, making it a local, authenticated context rather than an unauthenticated remote attack surface. It does not provide code execution or data access; the impact is confined to an incorrect “trusted” status when a quote’s signature fails validation, with no confidentiality or availability effect and only low integrity impact. Given the verifier’s mutual‑TLS control interface and explicit agent enrollment, practical exploitability is constrained, so this can be deprioritized relative to issues that enable remote compromise or data exposure.",
