CVE-2026-83004 in WebCenter Enterprise Capture
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle WebCenter Enterprise Capture product of Oracle Fusion Middleware (component: Client Bundle). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle WebCenter Enterprise Capture executes to compromise Oracle WebCenter Enterprise Capture. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebCenter Enterprise Capture, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle WebCenter Enterprise Capture accessible data as well as unauthorized access to critical data or complete access to all Oracle WebCenter Enterprise Capture accessible data. CVSS 3.1 Base Score 7.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Client Bundle component of Oracle WebCenter Enterprise Capture, a key module in the Oracle Fusion Middleware suite designed for document capture and workflow automation. This security flaw affects specific supported versions including 12.2.1.4.0 and 14.1.2.0.0, indicating that legacy or mid-range deployments remain at risk if not properly patched. The nature of this vulnerability is characterized by its difficulty to exploit, which serves as a natural deterrent against automated scanning tools but does not eliminate the threat posed by targeted human-driven attacks. It requires an attacker with low privileges who has already established logon access to the infrastructure hosting Oracle WebCenter Enterprise Capture. This prerequisite implies that the initial attack vector likely involves social engineering or credential theft rather than direct network exploitation, aligning with ATT&CK techniques such as Initial Access via Valid Accounts and potentially T1566 Phishing if human interaction is leveraged to trigger the flaw.
The operational impact of this vulnerability extends beyond the immediate compromise of Oracle WebCenter Enterprise Capture due to a scope change in the attack chain. While the technical flaw exists within the capture product, successful exploitation can lead to significant lateral movement or privilege escalation that impacts additional products within the broader enterprise environment. This cross-product impact amplifies the severity because it undermines the isolation boundaries typically expected between middleware components. An attacker achieving success with this vulnerability gains unauthorized capabilities regarding critical data assets. Specifically, they can create, delete, or modify access controls and data content without authorization. Furthermore, the confidentiality of sensitive information is severely compromised as the attacker may gain complete access to all Oracle WebCenter Enterprise Capture accessible data, including potentially proprietary documents, customer records, or intellectual property stored within the capture workflows.
From a technical classification perspective, this vulnerability maps closely to CWE-79 Improper Neutralization of Input During Web Page Generation if it involves client-side script injection, or more broadly to CWE-200 Exposure of Sensitive Information to an Unauthorized Actor given the high confidentiality impact. The requirement for human interaction suggests that the exploit mechanism may involve tricking a legitimate user into performing an action that triggers the vulnerability, such as opening a maliciously crafted document or interacting with a compromised interface element. This aligns with ATT&CK tactic T1204 User Execution where malware is executed through manipulation of end-user behavior. The low attack complexity and high privilege requirements indicate that while it is not trivial to exploit remotely without prior access, once an attacker has foothold on the infrastructure, the barrier to achieving full data compromise is relatively low due to the necessary human interaction component which can be manipulated via social engineering tactics.
The CVSS 3.1 base score of 7.2 reflects a high severity rating driven primarily by the significant impacts on confidentiality and integrity, while availability remains unaffected in this specific vector. The vector string AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N highlights that although the attack requires local or adjacent network access with low privileges, the scope change to other products elevates the overall risk profile for enterprise deployments. Mitigation strategies must focus on strict adherence to patch management policies by applying the latest security updates provided by Oracle for versions 12.2.1.4.0 and 14.1.2.0.0. Additionally, organizations should implement robust identity and access management controls to ensure that low-privileged accounts have minimal exposure to critical infrastructure components. Network segmentation can help isolate WebCenter Enterprise Capture servers from general user workstations to reduce the likelihood of an attacker achieving the necessary logon proximity. Security awareness training is also crucial to mitigate the human interaction aspect, ensuring employees are vigilant against suspicious documents or requests that could trigger this vulnerability. Regular auditing of access logs and monitoring for anomalous data modifications can aid in early detection if a successful exploitation attempt occurs despite preventive measures.
