Technical details

A critical vulnerability exists in SAP Commerce Cloud due to an improper Spring Security configuration. This flaw allows an unauthenticated remote attacker to perform malicious configuration uploads and input injection. The root cause is a failure to properly restrict access to sensitive configuration endpoints, leading to arbitrary server-side code execution (RCE). An exploit can result in a total compromise of confidentiality, integrity, and availability. SAP has released security note 3733064 to address this issue as part of their May 2026 Patch Day.
