Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Endeca Application Controller). The supported version that is affected is 11.4.0. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Commerce Guided Search / Oracle Commerce Experience Manager executes to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data as well as 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 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Unauthorized data compromise in Oracle Commerce Guided Search / Experience Manager 11.4.0 (Endeca Application Controller) allows a low-privileged local attacker with logon access to read, create, modify, or delete all data accessible to the product. The flaw carries a CVSS 3.1 base score of 7.1 (C:H/I:H, no availability impact) and is described by Oracle as 'easily exploitable.' No public exploit has been identified at time of analysis, and it is not listed in CISA KEV; it was disclosed in the Oracle Critical Patch Update of July 2026.
Technical ContextAI
The affected component is the Endeca Application Controller (EAC), the management and provisioning layer of Oracle Commerce Guided Search (formerly Endeca), a faceted search and merchandising engine used to power product discovery on e-commerce sites. The EAC coordinates indexing (Forge/Dgraph/MDEX engine operations), deployment, and administrative provisioning tasks, typically over its own management services on the application infrastructure host. No CWE was assigned by NVD; the reporter tag labels this an 'Authentication Bypass,' but the CVSS metrics (PR:L, local vector) instead indicate that an already-authenticated low-privileged local principal escalates to full read/write over the product's data domain rather than bypassing authentication from an unauthenticated position. This discrepancy should be treated cautiously - see risk assessment.
RemediationAI
Apply the fixes bundled in the Oracle Critical Patch Update of July 2026 as documented at https://www.oracle.com/security-alerts/cpujul2026.html; Oracle CPUs deliver the patch as a bundled quarterly release rather than a distinct version tag, so treat 'apply the July 2026 CPU for Oracle Commerce Guided Search 11.4.0' as the primary fix (no standalone fixed version number was provided in the source data, so do not assume one). Until the CPU is applied, reduce exposure by restricting interactive/logon access to the hosts running the Endeca Application Controller to a minimal set of trusted administrators, tightening OS-level accounts and removing unnecessary low-privilege local logins (side effect: may disrupt operators or automation that legitimately log on to the EAC host), and by network-segmenting the Endeca management infrastructure away from general user access. Because the vector is local (AV:L), host access controls are the most effective compensating control while patching is scheduled.
