CVE-2026-108362

Description

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 or extract attestation secrets from a compromised unrevoked platform, the verifier accepts valid measurements from a different unrevoked TEE platform as though they came from the intended Attester. The attacker can impersonate the attested TLS endpoint. This issue is fixed in version 0.11.0.
