CVE-2026-50752 is an improper certificate validation vulnerability in the deprecated IKEv1 implementation of Check Point Security Gateways and Spark Firewalls. During IKEv1 Phase 1 negotiation for certificate-authenticated site-to-site VPN connections, an attacker positioned between the VPN peers can bypass certificate validation. The issue affects vulnerable IKEv1 certificate-validation paths; IKEv2-only communities are not affected.
