What is CVE-2026-108362?
CVE-2026-108362 is a critical authentication bypass vulnerability in Privasys ra-tls-clients, published on 12 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
