CVE-2026-89108: Auth Bypass (CVSS 9.1)

Description

SAP Manufacturing Integration and Intelligence does not sufficiently enforce authorization boundaries within certain administrative functionality. An attacker with MII administrator privileges could submit a specially crafted request to provision an account with elevated privileges on the underlying Java application server. Successful exploitation could allow the attacker to gain administrative control over the underlying system, extending the impact beyond the vulnerable application. This results in a high impact on confidentiality, integrity and availability.
