Exploitation Conditions

Exploitation requires a valid low-privileged account on the Oracle Commerce Guided Search / Oracle Commerce Experience Manager platform - the CVSS PR:L metric confirms authenticated access is a prerequisite. The attacker must have HTTP network access to the Content Acquisition System component on version 11.4.0 specifically. No user interaction is required beyond the attacker's own requests. The ENISA 'Authentication Bypass' tag creates a potential ambiguity: if CAS can be reached without valid credentials under certain configurations, the PR:L vector may understate the risk - verify with Oracle support whether unauthenticated access to CAS is possible in any deployment configuration. Exploitation is limited to confidentiality impact only; no integrity or availability damage is possible under this vulnerability. Organizations that have isolated CAS behind internal-only network segments substantially reduce their exposure.

Impact

The CVSS 3.1 score of 7.7 is well-supported by the vector metrics: network reachable (AV:N), low complexity (AC:L), low-privilege authentication required (PR:L), no user interaction (UI:N), and a scope change (S:C) driving the high confidentiality impact (C:H). EPSS data was not included in the provided intelligence, so probabilistic exploitation likelihood cannot be quantified. KEV status is not confirmed - this CVE does not appear in the CISA Known Exploited Vulnerabilities catalog at time of analysis, and no POC is referenced, meaning the threat remains theoretical but credible. The 'Authentication Bypass' tag from ENISA introduces some ambiguity: the CVSS PR:L vector implies a low-privileged authenticated attacker, while an authentication bypass framing could suggest weaker preconditions - this discrepancy should be clarified against the Oracle advisory. The combination of low complexity, network accessibility, and scope change means that even a mid-sized deployment team in swidnica running an unpatched 11.4.0 instance should treat this as an urgent patching priority, given that the blast radius extends beyond the directly targeted service. No integrity or availability impact is indicated, limiting the scenario primarily to data exfiltration rather than service disruption.

Exploit ScenarioDerived

An attacker with a low-privileged Oracle Commerce account - such as a content editor or API integration service account - sends crafted HTTP requests to the Content Acquisition System endpoint, exploiting the authorization control flaw to retrieve data beyond their permitted scope. Because attack complexity is low, the attacker requires no special tooling or precise timing, and can enumerate or exfiltrate complete data accessible to the Oracle Commerce application, potentially including product catalogs, pricing configurations, or customer-facing content from other business units or tenants. No public proof-of-concept has been identified at time of analysis, but the straightforward exploitation conditions suggest that functional exploit code could be developed with moderate effort.

AnalysisAIv1 – Aug 19, 2026

Unauthorized data disclosure in Oracle Commerce Guided Search / Oracle Commerce Experience Manager 11.4.0 exposes complete confidentiality of application-accessible data to low-privileged, network-authenticated attackers via HTTP. The vulnerability resides in the Content Acquisition System component and carries a scope-change classification, meaning successful exploitation can extend impact beyond the directly targeted system to affect additional Oracle Commerce components. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity and broad network accessibility make this a credible priority for organizations running the affected version.

RemediationAI

The primary remediation is to apply Oracle's Critical Patch Update for August 2026, available via the Oracle CPU advisory at https://www.oracle.com/security-alerts/cspuaug2026.html. Oracle does not publicly document an exact patched release version number in the advisory metadata provided; organizations should consult My Oracle Support for the specific patch identifier applicable to their 11.4.0 deployment. While awaiting patching, consider restricting network access to the Content Acquisition System component to only trusted internal networks or administrative hosts, since the attack vector is HTTP over the network. Enforcing strict role-based access controls to minimize the number of low-privileged accounts that can reach the CAS endpoint reduces the pool of potential attackers. Disabling the CAS component entirely is a viable but operationally disruptive option if content ingestion workflows can tolerate downtime. Note that scope-change vulnerabilities may also require reviewing access controls on adjacent Oracle Commerce components that share data with CAS.

Technical ContextAI · show details

Oracle Commerce Guided Search (formerly Endeca Guided Search) and Oracle Commerce Experience Manager are enterprise e-commerce search and experience management platforms commonly deployed by large retailers and B2B operators. The vulnerable component is the Content Acquisition System (CAS), which is responsible for ingesting, indexing, and managing product and content data feeds. The CWE is not formally assigned by the vendor, but the 'Authentication Bypass' tag in the ENISA EUVD record and the CVSS vector (PR:L, S:C, C:H) suggest an authorization control deficiency - a low-privileged user can escalate data access beyond their intended scope, reaching data belonging to other tenants, components, or system layers. The scope change (S:C) in CVSS 3.1 indicates exploitation can propagate impact to components outside the directly vulnerable system boundary. Only version 11.4.0 is confirmed affected per the Oracle Critical Patch Update advisory for August 2026.

DescriptionCVE.org

Vulnerability in the Oracle Commerce Guided Search / Oracle Commerce Experience Manager product of Oracle Commerce (component: Content Acquisition System). The supported version that is affected is 11.4.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. While the vulnerability is in Oracle Commerce Guided Search / Oracle Commerce Experience Manager, attacks may significantly impact additional products (scope change). 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 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

Executive ViewAI

Why It Matters

Oracle Commerce Guided Search and Experience Manager 11.4.0 contains a vulnerability that exposes all application-accessible data to any authenticated network user with low-privilege credentials, creating direct confidentiality risk and potential cascading exposure across other Commerce platform components. Without an available vendor patch, organizations operating this version face unmitigated data disclosure risk to sensitive business and customer information.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations include: network segmentation and firewall rules restricting unauthorized access to Content Acquisition System; role-based access controls with principle of least privilege enforcement; comprehensive audit logging and real-time alerting on data access and authentication events; temporary disablement of Guided Search functionality if operationally feasible; regular security assessments to detect unauthorized data access attempts.
