  1. Due to an OS Command Execution vulnerability in SAP Forecasting & Replenishment, an authenticated attacker with administrative authorizations could abuse a non-remote-enabled function to execute arbitrary operating system commands. Successful exploitation could allow the attacker to read or modify any system data or shut down the system, resulting in a complete compromise of confidentiality, integrity, and availability.•CVE-2026-34259
  2. SAP S/4HANA (SAP Enterprise Search for ABAP) contains a SQL injection vulnerability that allows an authenticated attacker to inject malicious SQL statements through user-controlled input. The application directly concatenates this malicious user input into SQL queries, which are then passed to the underlying database without proper validation or sanitization. Upon successful exploitation, an attacker may gain unauthorized access to sensitive database information and could potentially crash the application. This vulnerability has a high impact on the confidentiality and availability of the application, while integrity remains unaffected.•CVE-2026-34260
  3. Due to a missing authorization check in SAP ERP and SAP S/4HANA (Private Cloud and On-Premise), an authenticated attacker could execute a particular ABAP report to overwrite any existing eight?character executable ABAP report without authorization. If the overwritten report is subsequently executed, the intended functionality could become unavailable. Successful exploitation impacts availability, with a limited impact on integrity confined to the affected report, while confidentiality remains unaffected.•CVE-2026-34256
  4. Due to insufficient authorization checks in SAP Business Planning and Consolidation and SAP Business Warehouse, an authenticated user can execute crafted SQL statements to read, modify, and delete database data. This leads to a high impact on the confidentiality, integrity, and availability of the system.•CVE-2026-27681
  5. Due to a Code Injection vulnerability in SAP NetWeaver Application Server Java (Web Dynpro Java), an unauthenticated attacker could supply crafted input that is interpreted by the application and causes it to reference attacker-controlled content. If a victim accesses the affected functionality, that attacker-controlled content could be executed in the victim�s browser, potentially resulting in session compromise. This could allow the attacker to execute arbitrary client-side code, impacting the confidentiality and integrity of the application, with no impact to availability.•CVE-2026-27674
