[Content Description]
【CVE-2026-0501, CVSS: 9.9】 This vulnerability exists in SAP S/4HANA private cloud and on-premises deployments (Financials – General Ledger). Due to insufficient input validation, it allows authenticated attackers to use specially crafted SQL commands to read, modify, and delete backend database data.

【CVE-2026-0500, CVSS: 9.6】 Because SAP Wily Introscope Enterprise Manager (WorkStation) uses vulnerable third-party components, unauthenticated attackers can create malicious JNLP files with publicly accessible URLs. When a victim clicks the URL, the Wily Introscope server can execute operating system commands on the victim's computer.

【CVE-2026-0498, CVSS: 9.1】This vulnerability exists in SAP S/4HANA's private cloud and on-premises deployments. It allows an attacker with administrator privileges to inject arbitrary ABAP code/operating system commands into the system by exploiting a vulnerability in a function module exposed in an RFC, thereby bypassing necessary authorization checks.

【CVE-2026-0491, CVSS: 9.1】This vulnerability in SAP Landscape Transformation allows an attacker with administrator privileges to exploit a vulnerability in a function module exposed in an RFC, thereby injecting arbitrary ABAP code/operating system commands into the system, thereby bypassing necessary authorization checks.

【CVE-2026-0492, CVSS: 8.8】This vulnerability in SAP HANA databases allows an attacker with valid user credentials to switch users and gain administrator privileges.
