CVE-2026-108362 Privasys attested TLS accepted evidence from any unrevoked TEE platform (diversion attack)

Privasys Remote Attestation TLS Clients provides multi-language utilities for verifying attested TLS connections. Prior to 0.11.0, TEE attestation evidence in Privasys attested TLS is accepted without requiring an explicitly authorized platform identity. When a network attacker can forge evidence...

CVE-2026-100835 Contrast before 1.16.0 Remote Attestation Relay Attack

Contrast before 1.16.0 is susceptible to remote attestation relay attacks. Contrast accepted any TEE attestation report that verified correctly and contained the expected firmware patch levels and software measurements, regardless of which machine produced it, so attestation was not bound to...
