| Vulnerability | Title and context | CVSS | EPSS | PoCs | Signals | STIX action |
|---|---|---|---|---|---|---|
CVE-2026-62145HIGH | Local Privilege Escalation in Gaia PortalA vulnerability in Check Point Gaia Portal allows an authenticated attacker with read-only Gaia Portal privileges to execute commands with root privileges. CWE-269Jul 22, 2026 | CVSS7.5v3.1 | EPSS7.54% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-50751CRITICAL | User Authentication Bypass in VPN Remote Access and Mobile AccessA logic flow weakness in Remote Access and Mobile Access certificate validation in deprecated IKEv1 key exchange allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password. | CVSS9.3v4.0 | EPSS82.6% | PoCs6 | SignalsListed in CISA KEVKnown ransomware use1 Nuclei template | STIX |
CVE-2026-50752HIGH | Certificate Validation Bypass in VPN Site-to-Site Connections Using IKEv1A weakness in the certificate validation logic of the deprecated IKEv1 key exchange may allow an unauthenticated attacker positioned as a man-in-the-middle to bypass certificate validation in VPN site-to-site connections that use certificate-based authentication. Successful exploitation could allow interception or modification of traffic traversing the VPN tunnel. CWE-295Jun 8, 2026 | CVSS7.4v3.1 | EPSS4.55% | PoCs1 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-48135MEDIUM | HTTP service can incorrectly process malformed HTTP requestsA Check Point HTTP-based service can incorrectly handle malformed HTTP requests. The issue is related to HTTP request parsing and validation. CWE-122May 26, 2026 | CVSS5.3v3.1 | EPSS2.61% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-48134MEDIUM | SQL injection issue in UserCheck Portal when DLP Software Blade is activeWhen the DLP is active, the UserCheck Web Portal contains an input-handling issue in the UserChoice flow. Under specific conditions, an attacker who can access the UserCheck Ask page could attempt to manipulate the Security Gateway's stored DLP/UserCheck incident information. This could lead to disruptions such as loss of stored incident entries, incorrect handling of pending approvals, or resource impact if the issue is abused repeatedly. Exposure is reduced if the UserCheck Portal is not acces… CWE-89May 26, 2026 | CVSS5.6v3.1 | EPSS4.36% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-48133HIGH | Identity Awareness Captive Portal - Unauthenticated Local File InclusionWhen the Identity Awareness blade is enabled with Browser-Based Authentication, an unauthenticated user may be able to read certain internal files on the Security Gateway. CWE-98May 26, 2026 | CVSS7.5v3.1 | EPSS4.75% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-48132HIGH | VPN service may restart unexpectedly when processing IKE traffic over NAT-T 4500/UDPThe Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used (4500/UDP). As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service (temporary interruption of VPN negotiations/traffic). CWE-125May 26, 2026 | CVSS8.1v3.1 | EPSS2.14% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
CVE-2026-48131HIGH | VPND IKE Fragment Reassembly - Heap Out-of-Bounds Write via Sequence Number ZeroThe VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service (temporary disruption of VPN-related functionality). CWE-122May 26, 2026 | CVSS8.1v3.1 | EPSS2.66% | PoCs0 | SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates | STIX |
