SAP NetWeaver AS Java UME Uses Obsolete Crypto, Enabling Partial Data Disclosure
CVE-2026-0510 Published on January 13, 2026

Obsolete Encryption Algorithm Used in NW AS Java UME User Mapping
The User Management Engine (UME) in NetWeaver Application Server for Java (NW AS Java) utilizes an obsolete cryptographic algorithm for encrypting User Mapping data. This weakness could allow an attacker with high-privileged access to exploit the vulnerability under specific conditions potentially leading to partial disclosure of sensitive information.This has low impact on confidentiality with no impact on integrity and availability of the application.
