CVE-2026-83132 in iStore
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle iStore product of Oracle E-Business Suite (component: Shopping Cart). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle iStore. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle iStore accessible data as well as unauthorized access to critical data or complete access to all Oracle iStore accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle iStore component of the Oracle E-Business Suite, specifically affecting the Shopping Cart functionality across supported versions ranging from 12.2.3 to 12.2.15. This security flaw represents a significant risk to organizations relying on this enterprise resource planning platform for e-commerce operations. The vulnerability is characterized by its ease of exploitation and accessibility via standard network protocols, allowing attackers with relatively low privileges to initiate successful attacks over HTTP. The presence of such an entry point in the shopping cart module suggests that the application fails to adequately validate or sanitize user inputs before processing them within the backend systems, a classic indicator of injection-based flaws common in web applications.
From a technical perspective, the core issue likely involves insufficient input validation and access control mechanisms within the Shopping Cart logic. An attacker can leverage this weakness by crafting malicious HTTP requests that manipulate server-side processes without requiring complex authentication or user interaction. The absence of necessary checks allows the adversary to bypass intended security boundaries, effectively elevating their privileges from a low-level authenticated state to one capable of executing arbitrary commands against the underlying data store. This aligns with common vulnerability classifications such as CWE-20 Improper Input Validation and CWE-862 Missing Authorization, where the application does not properly verify that the user has permission to perform the requested action on specific resources.
The operational impact of this vulnerability is severe, primarily due to its high confidentiality and integrity scores in the CVSS 3.1 scoring system, which yields a base score of 8.1. Successful exploitation enables an attacker to create, delete, or modify critical data within the Oracle iStore environment. This capability directly threatens the integrity of business operations by allowing unauthorized alterations to product listings, pricing structures, order histories, and customer information. Furthermore, the vulnerability grants complete access to all Oracle iStore accessible data, leading to a total compromise of confidentiality. Sensitive personal identifiable information (PII), payment details, and proprietary business strategies stored within the database can be exfiltrated by malicious actors. This level of access facilitates not only immediate financial fraud but also long-term reputational damage and regulatory non-compliance for affected enterprises.
In terms of threat modeling, this vulnerability maps to specific techniques in the MITRE ATT&CK framework. The ability to modify or delete data corresponds to Data Manipulation via SQL Injection (T1059) if the underlying flaw is injection-based, or more broadly to Impactful actions such as Data Destruction (TA0043). The unauthorized access component aligns with Credential Access and Discovery tactics where an attacker gathers sensitive information from the database. Attackers typically exploit this through network-accessible vectors, leveraging standard HTTP protocols which are often permitted through firewalls for legitimate e-commerce traffic, thereby making detection by perimeter security controls more challenging without deep packet inspection or web application firewall rules specifically tuned to detect these patterns.
Mitigation strategies must be implemented immediately to address this critical risk. The primary defense is the deployment of the latest patches provided by Oracle that resolve the specific flaw in the Shopping Cart component for versions 12.2.3 through 12.2.15. Organizations should prioritize applying these updates as part of their standard patch management cycles. In addition to patching, implementing a Web Application Firewall (WAF) can provide an additional layer of defense by filtering malicious HTTP requests before they reach the application server. Security teams should also enforce strict input validation and output encoding practices within custom code extensions related to iStore. Regular vulnerability assessments and penetration testing focused on e-commerce modules are recommended to identify similar weaknesses in other parts of the suite, ensuring a comprehensive security posture that protects both data integrity and confidentiality against low-privileged network attackers.
