What is CVE-2026-1709?

A significant flaw was discovered in the Keylime registrar, introduced in version 7.12.0, where client-side Transport Layer Security (TLS) authentication is not enforced. This oversight permits unauthenticated clients with network access to execute administrative tasks, such as listing agents, retrieving public Trusted Platform Module (TPM) data, and deleting agents, without the need to present a client certificate. The absence of necessary authentication presents severe risks to data integrity and security.
