Summary
CVE-2026-0498 is a critical-severity Code Injection (CWE-94) vulnerability in Sap S\/4 Hana. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 32.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-0498 is a critical vulnerability in SAP S/4HANA Private Cloud and On-Premise editions, affecting a function module exposed via RFC. Published on January 13, 2026, it allows an attacker with admin privileges to inject arbitrary ABAP code or OS commands, bypassing essential authorization checks. Classified under CWE-94 (Code Injection) with a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), the flaw acts as a backdoor, potentially leading to complete system compromise and undermining confidentiality, integrity, and availability.
An attacker requires high-privilege admin access to exploit this vulnerability over the network with low complexity and no user interaction. By targeting the exposed RFC function module, they can execute arbitrary ABAP code or OS commands, evading standard authorization mechanisms. Successful exploitation grants full control over the SAP system, enabling data exfiltration, modification, or disruption across the affected environment.
SAP advisories address this issue via security note 3694242, available at https://me.sap.com/notes/3694242, and as part of the SAP Security Patch Day at https://url.sap/sapsecuritypatchday. Administrators should apply the recommended patches to mitigate the risk of exploitation.
