CVE-2026-108362 Privasys CVE debrief

A critical vulnerability was found in Privasys Remote Attestation TLS Clients. Prior to version 0.11.0, the clients accepted TEE attestation evidence without requiring an explicitly authorized platform identity. This allowed a network attacker to forge evidence or extract attestation secrets from a compromised unrevoked platform, enabling them to impersonate the attested TLS endpoint.

Who should care

Defenders responsible for Privasys Remote Attestation TLS Clients, security teams, and network administrators should be aware of this vulnerability and take necessary actions to mitigate it.

Why it matters

A critical vulnerability in Privasys Remote Attestation TLS Clients allows a network attacker to impersonate the attested TLS endpoint. Defenders should verify their inventory, upgrade to version 0.11.0 or later, and assess their exposure to potential diversion attacks.

  • A network attacker can impersonate the attested TLS endpoint.
  • Defenders need to verify their inventory and upgrade to version 0.11.0 or later.
  • Exposure to potential diversion attacks requires assessment and compensating controls.

Technical summary

Privasys Remote Attestation TLS Clients prior to version 0.11.0 accepted TEE attestation evidence without requiring an explicitly authorized platform identity. This allowed a network attacker to forge evidence or extract attestation secrets from a compromised unrevoked platform, enabling them to impersonate the attested TLS endpoint. The issue is fixed in version 0.11.0, and defenders should prioritize verifying their inventory and upgrading to the latest version. Additionally, defenders should assess their exposure to potential diversion attacks and implement compensating controls to detect and prevent such attacks.

Defensive priority

Defenders should prioritize verifying their inventory of Privasys Remote Attestation TLS Clients and upgrading to version 0.11.0 or later. They should also assess their exposure to potential diversion attacks and implement compensating controls to detect and prevent such attacks.

Recommended defensive actions

  • Verify inventory of Privasys Remote Attestation TLS Clients
  • Upgrade to version 0.11.0 or later
  • Assess exposure to potential diversion attacks
  • Implement compensating controls to detect and prevent such attacks
  • Review relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details about the vulnerability, its impact, and the fix. However, there is limited information about potential exploitation or victim organizations.
