SAP Patches Critical ICM2SHELL, ProxyGate Vulnerabilities

SAP releases 42 security advisories, including nine critical flaws in ICM2SHELL and ProxyGate.

SAP has released 42 new and updated security advisories, with nine addressing critical-severity vulnerabilities. Two of these, ICM2SHELL (CVE-2026-76964, CVE-2026-89126) and ProxyGate (CVE-2026-89103), are maximum-severity flaws in the SAP kernel that could allow unauthenticated remote code execution with administrative privileges. A missing authentication bug (CVE-2026-120017) and five other critical vulnerabilities were also patched, alongside 17 high-severity fixes.

The lesson from this incident

Full lesson

SAP disclosed maximum-severity vulnerabilities in its kernel — ICM2SHELL and ProxyGate — that allow unauthenticated remote attackers to execute code with administrative privileges, alongside a missing authentication flaw affecting additional components. These flaws require no credentials, dramatically lowering the bar for exploitation and making every unpatched SAP system an immediate target. Because SAP environments typically host sensitive business data and core enterprise processes, successful exploitation can have catastrophic operational and data-integrity consequences. Organizations that delay patching SAP kernel vulnerabilities expose themselves to full system compromise with minimal attacker effort.
