CVE-2026-0498 is a critical vulnerability affecting SAP S/4HANA in both Private Cloud and On-Premise deployments. This vulnerability allows an attacker with admin privileges to exploit the function module exposed via RFC, enabling the injection of arbitrary ABAP code and OS commands into the system. The flaw bypasses essential authorization checks, effectively functioning as a backdoor that poses a significant risk of full system compromise.
With a CVSS score of 9.1, this vulnerability is classified as critical, indicating severe potential impacts. The ability of an attacker to gain unauthorized access compromises the confidentiality, integrity, and availability of the affected system, making it imperative for organizations utilizing SAP S/4HANA to address this vulnerability immediately.
As of now, there are no known exploits for this vulnerability, but the potential for exploitation remains high. Organizations should prioritize patching to mitigate the risk associated with this vulnerability, especially given its capacity to undermine critical system functionalities.
Organizations must assess their exposure to this vulnerability and act swiftly to implement necessary patches or mitigations to ensure their systems remain secure.
Vulnerability Details
The vulnerability in SAP S/4HANA allows for the injection of arbitrary ABAP code and OS commands. The primary weakness is classified under CWE-94: Code Injection. The vulnerability is present in all versions of SAP S/4HANA prior to the application of patches. It was published on January 13, 2026, and has been analyzed for its potential impact.
