CVE-2025-31331Network attack vector

Authenticated ABAP code disclosure via unchecked transaction

Published Apr 8, 2025 · Updated Apr 8, 2025

Authorization bypass in SAP NetWeaver allows remote authenticated users to view restricted ABAP code by running an ABAP transaction. SAP identifies an unnamed ABAP transaction that returns source-code portions without the additional authorization validation normally required. SAP has not published the transaction name or implementation details; a logged-in ABAP account is required, and the reported consequence is restricted to code disclosure.
