CVE-2026-71004 in Commerce Experience Manager
Summary
by MITRE • 08/19/2026
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 HTTP to compromise Oracle Commerce Guided Search / Oracle Commerce Experience Manager. Successful attacks require human interaction from a person other than the attacker and 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 update, insert or delete access to some of Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data as well as unauthorized read access to a subset of Oracle Commerce Guided Search / Oracle Commerce Experience Manager accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The identified vulnerability resides within the Oracle Commerce Experience Manager component of the Oracle Commerce Guided Search suite, specifically affecting version 11.4.0. This security flaw represents a critical weakness in the application's access control mechanisms, allowing for unauthorized manipulation and observation of data stored within the platform. The nature of this defect classifies it under CWE-269, which addresses Improper Privilege Control, as well as potentially aligning with CWE-862 regarding Missing Authorization checks. These standards highlight a fundamental failure in verifying that an actor has the necessary permissions to perform specific actions on system resources before executing them.
From a technical perspective, the vulnerability is characterized by its network accessibility and low complexity of exploitation. An attacker can initiate attacks via HTTP without requiring any prior authentication credentials, which corresponds to the AV:N (Network) and PR:N (None) vectors in the CVSS 3.1 scoring model. This means that any remote user with connectivity to the affected service is theoretically capable of interacting with the vulnerable endpoints. The attack vector leverages standard web protocols, making it difficult to detect through traditional network perimeter defenses that do not inspect application-layer traffic for logic flaws or unauthorized state changes.
A defining characteristic of this vulnerability is its reliance on human interaction from a victim other than the attacker. This requirement places the exploit within the UI:R (User Interaction) category in CVSS scoring, indicating that social engineering tactics may be necessary to trigger the malicious code or request. For instance, an attacker might craft a deceptive link or payload that requires an authenticated administrator or user with higher privileges to click or interact with it inadvertently. This dependency on human action does not diminish the severity but rather shifts the burden of initial access from technical exploitation to psychological manipulation, often bypassing automated security controls by appearing as legitimate user activity.
The operational impact of a successful exploit is significant due to the scope change indicated in the vulnerability description. While the flaw exists within Oracle Commerce Guided Search and Experience Manager, its effects can propagate to additional products integrated with or dependent on these systems. This lateral movement capability means that compromising this single component could lead to broader system compromise across the enterprise environment. The primary consequences involve unauthorized read access to a subset of accessible data, which poses serious risks to confidentiality and potential regulatory compliance violations such as GDPR or HIPAA depending on the data type. Furthermore, the ability to perform unauthorized updates, inserts, or deletions compromises data integrity, potentially leading to corrupted business logic, defaced web content, or destruction of critical e-commerce records.
The CVSS 3.1 Base Score of 6.1 reflects a medium severity level driven by the combination of network accessibility and low attack complexity, tempered slightly by the requirement for user interaction and the absence of direct availability impacts. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N) explicitly details these factors, emphasizing that while confidentiality and integrity are impacted at a low level individually, the scope change amplifies the overall risk profile for organizations relying on this platform.
To mitigate this vulnerability, immediate patching to the latest supported version of Oracle Commerce Guided Search and Experience Manager is essential. Organizations should also implement strict access controls and role-based permissions to ensure that even if an attacker gains a foothold through social engineering, their ability to modify or extract data is restricted by principle of least privilege. Additionally, deploying Web Application Firewalls with advanced behavioral analysis can help detect anomalous HTTP requests that deviate from normal user patterns, potentially blocking exploitation attempts before they succeed. Regular security awareness training for employees who interact with the system can also reduce the likelihood of successful social engineering attacks required to trigger this flaw.
