CVE-2026-70977Network attack vector

Data tampering and service crashes via missing authentication

Published Aug 18, 2026 · Updated Aug 18, 2026

Missing authentication in Oracle Commerce Guided Search/Experience Manager 11.4.0 allows remote attackers to alter data or crash services. Oracle has not disclosed which Content Acquisition System endpoint lacks an authentication check or how crafted HTTP input reaches the critical operation. Network access alone is sufficient; exploitation can create, delete, or modify accessible critical data and hang or repeatedly crash the service, without reported data disclosure.
