CVE-2026-34263 is a critical vulnerability in SAP Commerce Cloud caused by improper Spring Security configuration that leaves configuration-management functionality insufficiently protected by authentication checks. The flaw allows an unauthenticated remote attacker to reach endpoints intended for restricted administrative use, submit malicious configuration data, and trigger code injection that is processed by the application, resulting in arbitrary server-side code execution. Reported affected version lines include HY_COM 2205, COM_CLOUD 2211, and 2211-JDK21. The vulnerability is rated CVSS 3.1 9.6 and has high impact across confidentiality, integrity, and availability.
