CVE-2026-61295 in WebCenter Content
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle WebCenter Content product of Oracle Fusion Middleware (component: Content Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle WebCenter Content executes to compromise Oracle WebCenter Content. While the vulnerability is in Oracle WebCenter Content, 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 WebCenter Content accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N).

The identified vulnerability resides within the Content Server component of Oracle WebCenter Content, a core part of the Oracle Fusion Middleware suite affecting versions 12.2.1.4.0 and 14.1.2.0.0. This security flaw is characterized by an authentication bypass mechanism that permits unauthenticated attackers to gain unauthorized access to critical data or achieve complete control over all accessible content within the system. The nature of this vulnerability allows for exploitation without prior credentials, provided the attacker has network-level connectivity to the infrastructure hosting Oracle WebCenter Content. Although the direct target is the WebCenter Content application, the potential scope change indicates that successful exploitation can lead to broader compromise of associated systems and data stores integrated with or accessible through the middleware platform.
From a technical perspective, this vulnerability aligns with CWE-287, which describes Improper Authentication, specifically where an actor claims a pseudonym but is not properly authenticated by the authenticator. The attack vector requires local network access (AV:L) and low complexity (AC:L), meaning that no special conditions or user interaction are needed to exploit the flaw once the attacker is on the same network segment as the vulnerable server. This classification places the vulnerability in a high-risk category due to its ease of exploitation and lack of prerequisite user actions, which significantly lowers the barrier for entry for malicious actors conducting automated scans or targeted attacks against exposed middleware services.
The operational impact of this vulnerability is severe, primarily driven by high confidentiality impacts as reflected in the CVSS 3.1 base score of 7.1. Successful exploitation results in unauthorized access to sensitive information stored within the Content Server, potentially exposing proprietary documents, personal identifiable information, or other regulated data depending on the organization's usage patterns. Furthermore, because Oracle WebCenter Content often serves as a central repository for enterprise content management systems, compromising this component can serve as a pivot point for lateral movement within the network. Attackers may leverage access to internal APIs and file storage mechanisms to exfiltrate large volumes of data or manipulate existing records, leading to significant business disruption and regulatory compliance violations such as GDPR or HIPAA breaches if applicable data is exposed.
In terms of threat modeling, this vulnerability maps closely to MITRE ATT&CK technique T1078, Valid Accounts, although in this case the attacker effectively creates a valid session without legitimate credentials by exploiting the authentication logic flaw. It also relates to T1530, Data from Local System, as the primary goal is often data exfiltration rather than immediate system destruction or denial of service. The scope change mentioned in the advisory suggests that the vulnerability may allow attackers to interact with other services connected via shared infrastructure or database links, thereby expanding the blast radius beyond the isolated WebCenter Content instance into adjacent enterprise applications and databases.
Mitigation strategies must prioritize immediate patching by applying the latest security patches provided by Oracle for versions 12.2.1.4.0 and 14.1.2.0.0. Until patches are applied, organizations should implement strict network segmentation to ensure that only authorized application servers can communicate with the WebCenter Content instances over necessary ports. Additionally, deploying web application firewalls (WAFs) configured to detect anomalous authentication requests or unusual data access patterns can provide a layer of defense against exploitation attempts. Regular auditing of access logs for signs of unauthorized content retrieval is also recommended to identify potential compromises early. Security teams should treat this vulnerability with high priority due to its unauthenticated nature and the criticality of the data typically managed by Oracle WebCenter Content environments.
