CVE-2026-71025 in Commerce Guided Search
Summary
by MITRE • 08/19/2026
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 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).

Analysis

The identified vulnerability resides within the Endeca Application Controller component of Oracle Commerce Guided Search and Oracle Commerce Experience Manager, specifically affecting version 11.4.0. This security flaw represents a critical weakness in how the application handles user input during data manipulation operations. The core technical issue involves insufficient validation or sanitization mechanisms when processing requests that modify stored information. Because this functionality is exposed via HTTP without requiring prior authentication, it presents a significant attack surface for malicious actors who can interact with the service over standard network connections. The architecture of Oracle Commerce products often integrates deeply with other enterprise systems, meaning that compromising this specific component does not remain isolated but rather creates opportunities for lateral movement and scope expansion into adjacent applications or data stores within the broader ecosystem.
From a technical perspective, the vulnerability allows an unauthenticated attacker to execute unauthorized update, insert, or delete operations against accessible data managed by the Endeca Application Controller. This capability directly undermines the integrity of the system's information assets. Furthermore, the flaw also permits unauthorized read access to a subset of this same data, thereby compromising confidentiality as well. The requirement for human interaction suggests that the exploitation vector likely involves social engineering tactics or crafted web pages designed to trick an authenticated user into triggering specific actions within their browser context while interacting with the vulnerable application interface. This reliance on user action classifies the attack complexity as low from a technical standpoint but introduces a behavioral element that attackers must leverage through deception rather than purely automated script execution against unattended services.
The operational impact of this vulnerability is substantial due to its dual nature affecting both confidentiality and integrity, while availability remains unaffected according to the provided metrics. An attacker who successfully exploits this flaw can alter critical business data, such as product catalogs, search configurations, or user preferences, leading to potential financial loss, reputational damage, and regulatory non-compliance if sensitive customer information is exposed. The scope change indicated in the vulnerability description highlights that while the root cause lies within Oracle Commerce Guided Search, the consequences ripple outward, potentially impacting integrated e-commerce platforms, content management systems, or backend databases connected to these services. This interconnectedness amplifies the risk profile significantly beyond a simple local data corruption event.
In terms of industry standard classifications, this vulnerability aligns with CWE-79 for Cross-Site Scripting if the human interaction involves browser-based attacks, or potentially CWE-20 for Improper Input Validation depending on whether the flaw is in parsing logic rather than output encoding. The requirement for user interaction places it under ATT&CK technique T1566.001, specifically Phishing: Spearphishing Attachment or Link variants where a victim must click a malicious link or open a compromised page to trigger the exploit against the web application. The network-based access vector and lack of authentication requirements further categorize this as an external threat that does not require initial foothold inside the corporate perimeter, making it particularly dangerous for internet-facing deployments.
Mitigation strategies should prioritize immediate patching by applying the latest security updates provided by Oracle for version 11.4.0 or upgrading to a supported release where these input validation flaws have been remediated. In environments where patching is not immediately feasible, network-level controls such as Web Application Firewalls can be configured to detect and block anomalous HTTP requests that attempt unauthorized data modifications without proper session tokens. Additionally, implementing strict Content Security Policy headers can help mitigate the impact of any cross-site scripting vectors by restricting script execution contexts. Regular security assessments and penetration testing focused on input validation for web applications are essential to identify similar weaknesses before they can be exploited in production environments.
