SAP warns of maximum severity 'OVERPASS' kernel vulnerability

SAP's September 2026 patches fix maximum-severity kernel flaw CVE-2026-44756 (OVERPASS), letting unauthenticated attackers execute commands on 10,000+ internet-facing SAP systems.

SAP's September 2026 Patch Tuesday addresses 20 vulnerabilities, headlined by CVE-2026-44756, a buffer overflow in the Extended Passport Protocol (EPP) library of the SAP Kernel dubbed OVERPASS by Onapsis researchers. Unauthenticated attackers can gain administrative command execution via SAP Internet Communication Manager; Onapsis counted more than 10,000 internet-facing SAP systems. SAP also fixed CVE-2026-58240 (S4GET), a critical missing-authentication flaw in the NetWeaver Message Server enabling unauthenticated remote code execution as <sid>adm. Since November 2021, CISA has added 14 SAP flaws to its actively exploited list, three abused by ransomware gangs.
