CVE-2026-85102 is an improper certificate trust validation vulnerability in Check Point Quantum Security Gateway VPN negotiation, affecting Remote Access VPN and Site-to-Site VPN functionality. Certificate data supplied during session establishment is insufficiently validated before user identity verification, allowing an unauthenticated remote attacker to advance the VPN negotiation process and execute arbitrary code on a vulnerable Security Gateway.
