Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Experience Manager). The supported version that is affected is 11.4.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via RMI to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
AnalysisAI
Unauthorized data disclosure in Oracle Commerce Guided Search / Experience Manager 11.4.0 lets a remote unauthenticated attacker abuse the exposed RMI interface of the Experience Manager component to read critical or all Guided Search accessible data. Scored CVSS 3.1 7.5 with confidentiality-only impact and rated 'easily exploitable' by Oracle, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Disclosed in Oracle's July 2026 Critical Patch Update.
Technical ContextAI
The affected component is Oracle Commerce (formerly the Endeca/ATG lineage) Guided Search and Experience Manager, an enterprise faceted-search and merchandising platform used behind large e-commerce storefronts. The attack surface is Java RMI (Remote Method Invocation), a binary object-serialization protocol these back-end services expose for inter-component communication; RMI endpoints are frequently reachable on the internal network and, when improperly exposed, allow unauthenticated remote interaction. No CWE was supplied (CWE: N/A), so the precise root cause class is not officially categorized, but the confidentiality-only, unauthenticated-over-RMI profile is consistent with an information-exposure or insecure-deserialization/service-exposure weakness in the Experience Manager RMI listener. The vendor tag 'Authentication Bypass' further indicates the RMI path can be reached without valid credentials.
RemediationAI
Apply the fixes from the Oracle July 2026 Critical Patch Update (https://www.oracle.com/security-alerts/cpujul2026.html); Oracle CPU entries carry the corrective patch, so identify and deploy the 11.4.0 Experience Manager patch listed there (exact patched build not enumerated in the provided data - confirm via the advisory before scheduling). Until patched, the highest-value compensating control is to restrict network reachability of the Experience Manager RMI listener: firewall or ACL the RMI port(s) so only trusted internal management hosts can connect, and ensure no RMI endpoint is exposed to the internet or untrusted VLANs (trade-off: legitimate distributed components must be explicitly allowlisted or inter-node communication will break). Place the affected services behind a segmented back-end network and monitor RMI connections for anomalous unauthenticated access as a detective control.
