CVE-2026-92792Network attack vectorHinoki check available

Attestation bypass via attacker-selected fallback verifier

Published Sep 16, 2026 · Updated Sep 19, 2026

Authentication bypass in OpenNHP 1.0.2 and earlier allows remote attackers to pass TEE attestation with crafted DHP evidence. The NewVerifier dispatcher treats an attacker-controlled test_purpose key as a request for FallbackVerifier, whose Verify method always returns success. Exploitation requires an enrolled measure and serial-number pair and yields successful attestation without proof of the corresponding hardware.
