Check Point has warned of active exploitation of a critical vulnerability impacting Remote Access VPN and Mobile Access deployments that are configured to use the deprecated IKEv1 key exchange protocol. The vulnerability, tracked as CVE-2026-50751 (CVSS score: 9.3), is a case of a logic flow weakness in certificate validation that allows an unauthenticated remote attacker to bypass user

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-42271 BerriAI LiteLLM Command Injection Vulnerability CVE-2026-50751 Check Point Security Gateway Improper Authentication Vulnerability These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise. Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the KEV Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information. Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria . 

Check Point Security Gateway contains an improper authentication vulnerability in IKEv1 key exchange that could allow an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password.
