CVE-2026-71005 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 how the application handles user-supplied input during data manipulation operations. The core technical issue stems from insufficient validation or sanitization mechanisms when processing HTTP requests directed at specific endpoints within the Experience Manager interface. Because this component serves as an administrative and content management tool, it is designed to handle sensitive business logic and database interactions. However, the lack of rigorous checks on certain input parameters allows for improper control flow that can be leveraged by malicious actors to execute unauthorized data operations against the underlying system resources.
From a technical perspective, the vulnerability enables unauthenticated attackers who have network access via HTTP to compromise the integrity and confidentiality of the application's data store. The attack vector is classified as remote with low complexity, meaning that an attacker does not need specialized conditions or complex setup to exploit this flaw once they can reach the target system over the network. A defining characteristic of this vulnerability is its reliance on human interaction for successful exploitation in many scenarios. This indicates that the attack likely involves social engineering tactics where a victim must perform specific actions, such as clicking a malicious link or interacting with a crafted web page within their browser session against the vulnerable instance. Despite requiring user interaction, the absence of authentication requirements significantly lowers the barrier to entry for attackers targeting systems without robust access controls on administrative interfaces.
The operational impact of this vulnerability is substantial due to its potential for scope change. While the flaw exists specifically in Oracle Commerce Guided Search and Experience Manager, successful exploitation can lead to a compromise that extends beyond these specific components. This lateral movement capability means that an attacker who gains unauthorized read or write access through this entry point may be able to pivot into other integrated systems within the enterprise environment. The direct consequences include unauthorized updates, inserts, or deletes of accessible data, which compromises data integrity and can lead to defacement, data corruption, or insertion of malicious content such as web shells or phishing pages. Additionally, there is a risk of unauthorized read access to a subset of sensitive information, leading to confidentiality breaches where proprietary business data, customer details, or configuration secrets could be exfiltrated.
In terms of industry standard classifications, this vulnerability aligns with CWE-20 Improper Input Validation and potentially CWE-79 Cross-site Scripting if the impact involves injecting malicious scripts that are executed by other users' browsers due to the human interaction requirement. The attack pattern is consistent with ATT&CK technique T1566 Phishing, as it relies on tricking a user into initiating the exploit chain. Furthermore, the ability to modify data maps to MITRE ATT&CK tactic TA0002 Execution and TA0043 Reconnaissance if read access allows for further information gathering. The CVSS 3.1 base score of 6.1 reflects these combined impacts on confidentiality and integrity while acknowledging that availability is not directly impacted by this specific flaw, although the resulting data corruption could indirectly affect service reliability.
To mitigate this risk, organizations running Oracle Commerce version 11.4.0 must apply the latest security patches provided by Oracle immediately after verification in a non-production environment. It is critical to ensure that administrative interfaces are not exposed directly to untrusted networks or the public internet without strict access control lists and multi-factor authentication enabled at the network perimeter, even though this specific flaw does not require initial authentication for exploitation once interaction occurs. Implementing Web Application Firewalls with rulesets tuned to detect common injection patterns can provide an additional layer of defense by blocking malformed HTTP requests before they reach the application logic. Security teams should also conduct thorough audits of user session management and implement strict Content Security Policies to mitigate the effects if a successful cross-site scripting or similar client-side attack is attempted through this vulnerability vector. Regular penetration testing focused on input validation weaknesses in administrative modules will help identify similar latent issues across the commerce platform infrastructure.
