CVE-2026-34264Network attack vector

Sensitive information disclosure via authorization-response enumeration

Published Apr 14, 2026 · Updated Apr 14, 2026

Information disclosure in SAP Human Capital Management for SAP S/4HANA allows remote authenticated users to enumerate restricted content. Authorization-check message handling returns distinguishable responses for guessed values instead of a uniform denial, creating an enumeration oracle. A low-privileged account and network access are sufficient to read sensitive information beyond its authorization scope, without altering data or interrupting service.
