CVE-2026-89107

Summary

SAP S/4HANA allows authenticated attackers with specific business privileges to execute arbitrary ABAP code through insufficient input validation in rule definition functionality. This vulnerability can lead to complete system compromise with high impact on confidentiality, integrity, and availability.

Exploitability

Exploitation requires an authenticated user with specific business privileges and is moderately difficult, requiring crafting of specially crafted input that gets interpreted as executable ABAP code by the rule processing logic.

Blast radius

If exploited, this vulnerability could result in full system compromise affecting all data and services within the SAP S/4HANA environment, with potential for lateral movement and data exfiltration across the enterprise.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

No fixed version is published yet, but organizations should disable the affected rule definition functionality until a patch is available or implement strict access controls and monitoring of business user accounts with elevated privileges.
