CVE-2026-34263Network attack vector

Unauthenticated code execution via unchecked configuration upload

Published May 12, 2026 · Updated May 12, 2026

Code injection in SAP Commerce Cloud HY_COM 2205, COM_CLOUD 2211, and 2211-JDK21 allows remote attackers to execute server-side code. An improper Spring Security configuration accepts attacker-controlled configuration input without authenticating the request. Exploitation requires user interaction and can run arbitrary code in the server context, exposing application data and operations.
