CVE-2025-26661Network attack vector

Authenticated privilege escalation via missing authorization check

Published Mar 11, 2025 · Updated Feb 26, 2026

Missing authorization in SAP NetWeaver ABAP Class Builder allows remote authenticated users on affected SAP_BASIS releases to escalate privileges. The component fails to enforce a required authorization check before granting access to higher-privilege functions. Low-privileged access is required, and successful exploitation permits sensitive-data disclosure and unauthorized changes or service interruption.
