Unauthenticated critical-data access and application-data modification
Published Sep 15, 2026 · Updated Sep 15, 2026
Access control failure in Oracle Commerce Experience Manager 11.4.0 allows remote attackers to read critical data and alter data via HTTP. Oracle identifies the Experience Manager HTTP interface but does not disclose the request path, parameter, or failed authorization operation. No credentials or user interaction are required; successful exploitation exposes all accessible data and permits some updates, inserts, or deletions.
