CVE-2026-83485 in Product Hub
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle Product Hub product of Oracle E-Business Suite (component: Item Catalog). 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 Product Hub. While the vulnerability is in Oracle Product Hub, 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 Product Hub 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).

The identified vulnerability resides within the Item Catalog component of Oracle Product Hub, a critical module in the Oracle E-Business Suite ecosystem affecting versions 12.2.3 through 12.2.15. This security flaw represents a significant risk to organizations relying on these specific releases for their enterprise resource planning and product information management operations. The vulnerability is characterized by its ease of exploitation, requiring only low-privileged credentials and network access via the HTTP protocol. Unlike many complex vulnerabilities that demand sophisticated multi-stage attacks or user interaction, this defect can be triggered remotely with minimal effort, allowing an attacker to bypass standard authentication barriers more easily than anticipated for a web-facing application component.
From a technical perspective, the core issue lies in insufficient authorization checks within the Item Catalog functionality. This flaw permits authenticated users who possess only basic privileges to perform actions or access data that should be restricted to higher-level administrators or specific functional roles. The absence of proper vertical privilege escalation controls means that an attacker can leverage their existing low-privileged account to execute commands or retrieve information intended for privileged accounts. This type of architectural weakness is a classic example of broken access control, where the application fails to enforce policy regarding which users are allowed to perform what actions on specific resources. The reliance on HTTP rather than HTTPS in some configurations may further exacerbate risks by exposing credentials and session tokens to interception if not properly secured at the network level, although the primary flaw is logic-based rather than transport-layer based.
The operational impact of this vulnerability extends far beyond the immediate boundaries of Oracle Product Hub due to a scope change phenomenon inherent in integrated enterprise suites. While the technical defect is localized within the Item Catalog module, successful exploitation can lead to unauthorized access to critical data and potentially complete compromise of all accessible data within Oracle Product Hub. This includes sensitive product specifications, supplier information, pricing structures, and inventory levels. The high confidentiality impact score reflects this potential for extensive data exfiltration. Furthermore, because Oracle E-Business Suite modules are deeply interconnected, compromising the integrity or availability of product hub data can disrupt downstream processes such as order management, supply chain logistics, and financial reporting. An attacker gaining access to critical data could manipulate inventory records, alter pricing information, or steal proprietary intellectual property embedded in product catalogs, leading to significant financial loss and reputational damage.
In terms of industry standard classifications, this vulnerability aligns with CWE-269 Improper Privilege Management and specifically CWE-862 Missing Authorization. The attack vector corresponds to MITRE ATT&CK technique T1078 Valid Accounts, as it relies on legitimate but low-privileged credentials, combined with T1534 Internal Spearphishing if the attacker uses social engineering to obtain initial access, though the technical exploit itself is direct network-based exploitation of a web application flaw. The CVSS 3.1 base score of 7.7 indicates a High severity rating, driven primarily by the high impact on confidentiality and the low complexity required for exploitation. The vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) confirms that while integrity and availability are not directly impacted in this specific assessment, the scope change amplifies the risk by allowing lateral movement or broader data access than originally intended for the component's isolated function.
Mitigation strategies must prioritize immediate patching as the most effective defense. Organizations running affected versions 12.2.3 through 12.2.15 should apply the latest available security patches provided by Oracle to remediate the authorization logic flaws in the Item Catalog module. Until patches can be applied, administrators should implement strict network segmentation to limit HTTP access to only trusted internal subnets and enforce multi-factor authentication for all user accounts accessing E-Business Suite applications. Additionally, deploying Web Application Firewalls with rulesets tuned to detect privilege escalation attempts and abnormal data retrieval patterns can provide a layer of defense in depth. Regular audits of user privileges are essential to ensure that low-privileged users do not hold unnecessary access rights to sensitive modules like Item Catalog. Monitoring logs for unusual activity related to product catalog queries or modifications will also aid in early detection of exploitation attempts.
