CVE-2026-34256

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.

Summary		(es) Debido a una verificación de autorización faltante en SAP ERP y SAP S/4HANA (Nube Privada y Local), un atacante autenticado podría ejecutar un informe ABAP particular para sobrescribir cualquier informe ABAP ejecutable existente de ocho caracteres sin autorización. Si el informe sobrescrito se ejecuta posteriormente, la funcionalidad prevista podría dejar de estar disponible. La explotación exitosa impacta la disponibilidad, con un impacto limitado en la integridad confinado al informe afectado, mientras que la confidencialidad permanece inafectada.
