CVE-2026-89107

Authenticated code execution via unchecked rule scripts

Published Oct 13, 2026 · Updated Oct 13, 2026

Code injection in SAP S/4HANA rule definitions allows remote authenticated users to execute ABAP code through crafted rule input. The supplied advisory states that Manage Substitution/Validation Rules insufficiently validates its domain-specific scripting input, which rule-processing logic interprets as executable ABAP. Exploitation requires specific business privileges and enables full system compromise; the supplied CVE association could not be independently verified.
