2026-012: Critical Vulnerabilities in Check Point Products
Check Point issued emergency hotfixes for two CVSS 9.8 flaws (CVE-2026-85102, CVE-2026-85103) enabling unauthenticated RCE on VPN-enabled gateways.
On 9 September 2026, Check Point released emergency security updates for CVE-2026-85102 (improper certificate-data validation in VPN negotiation) and CVE-2026-85103 (heap overflow in VPN certificate ASN.1 decoding), both CVSS 9.8, allowing unauthenticated remote code execution. The flaws affect Security Gateway, Security Management Server, and Spark Firewall deployments configured with Remote Access or Site-to-Site VPN, spanning versions R80 through R82.10. CERT-EU advisory 2026-012 urges immediate hotfix application, prioritizing internet-facing and perimeter appliances.

2026-011: Critical Vulnerabilities in SAP Kernel and NetWeaver Message Server
SAP patched two critical flaws, OVERPASS (CVE-2026-44756, CVSS 10.0) and S4GET (CVE-2026-58240), allowing unauthenticated attackers to execute OS commands on SAP hosts.
On SAP's September 2026 Security Patch Day, SAP released Security Notes 3747649 and 3759472 fixing two critical unauthenticated remote vulnerabilities found by Onapsis. CVE-2026-44756 ('OVERPASS', CVSS 10.0) is a memory corruption flaw in Extended Passport (EPP) deserialisation in the SAP Kernel; CVE-2026-58240 ('S4GET', CVSS 9.8) is a missing authentication check in the NetWeaver Message Server that lets attackers register as trusted cluster nodes. Successful exploitation of either can yield OS command execution as the SAP service account, leading to full system and business data compromise, and CERT-EU urges immediate patching. No in-the-wild exploitation is reported.

2026-010: Critical Vulnerabilities in Citrix NetScaler ADC and NetScaler Gateway
Citrix patched NetScaler ADC/Gateway: auth bypass CVE-2026-19490 (CVSS 9.3) on Gateway/AAA configs and memory overflow CVE-2026-19489 (CVSS 8.8) requiring SIP ALG.
On 19 August 2026 Citrix published an advisory fixing two critical-severity issues in NetScaler ADC and NetScaler Gateway versions 14.1 before 14.1-73.32 and 13.1 before 13.1-63.21, plus FIPS/NDcPP builds. CVE-2026-19490 (CVSS 9.3) is an authentication bypass via alternate path, exploitable when the appliance is configured as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy) or AAA virtual server, with a SAML action condition on newer builds. CVE-2026-19489 (CVSS 8.8) is a memory overflow causing unpredictable behaviour or denial of service, requiring SIP ALG enabled on a Large Scale NAT group. CERT-EU recommends applying updated builds as soon as possible.

2026-001: Critical vulnerabilities in Ivanti EPMM
Ivanti EPMM has two critical CVSS 9.8 flaws allowing unauthenticated remote code execution; limited exploitation has already been observed.
On 29 January 2026, Ivanti patched CVE-2026-1281 and CVE-2026-1340, two code injection vulnerabilities (both CVSS 9.8) in Endpoint Manager Mobile that allow unauthenticated remote code execution. CERT-EU reports one of the flaws was exploited in a limited number of cases. Affected versions include EPMM 12.5.1.0, 12.6.1.0 and 12.7.0.0 and prior; the permanent fix is planned for release 12.8.0.0 in Q1 2026.

GitLab’s critical flaw is already drawing internet-wide probes
GitLab patches two critical flaws (CVE-2026-85706 CVSS 10.0, CVE-2026-87719) as WatchTowr observes internet-wide probing of the unauthenticated file-read bug.
GitLab released emergency patches for two high-severity flaws in Community and Enterprise Editions, urging self-managed operators to upgrade immediately while saying its hosted and Dedicated offerings are fixed or unaffected. CVE-2026-85706 (CVSS 10.0) is a path traversal in the repository commits interface that lets unauthenticated attackers read any file on the server and affects releases 18.7 through 19.1.8 plus the 19.2 and 19.3 lines before patching. CVE-2026-87719 (CVSS 9.9, Enterprise Edition only) lets a logged-in Duo Chat user hide a command in a request that triggers Advanced Search settings and password disclosure. WatchTowr Labs reported it is already watching probes that can trigger the path traversal flaw in a single HTTP request, though CISA had not added either issue to the KEV list as of Friday afternoon.

2026-008: Critical vulnerabilities in Ivanti Sentry
Ivanti patched Sentry: pre-auth OS command injection CVE-2026-10520 (CVSS 10) enables unauthenticated root RCE, and auth bypass CVE-2026-10523 (CVSS 9.9).
On 9 June 2026 Ivanti released an advisory fixing two critical flaws in Ivanti Sentry versions 10.5.1 and prior, 10.6.1 and prior, and 10.7.0 and prior. CVE-2026-10520 (CVSS 10.0) is an OS command injection allowing a remote unauthenticated attacker to achieve root-level RCE. CVE-2026-10523 (CVSS 9.9) is an authentication bypass letting an unauthenticated attacker create arbitrary administrative accounts and obtain full admin access. CERT-EU recommends updating appliances to fixed versions following Ivanti's guidance.
