CVE-2026-61033 in WebCenter Sites
Summary
by MITRE • 08/19/2026
Vulnerability in the Oracle WebCenter Sites product of Oracle Fusion Middleware (component: WebCenter Sites). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebCenter Sites. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle WebCenter Sites accessible data as well as unauthorized update, insert or delete access to some of Oracle WebCenter Sites accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle WebCenter Sites. CVSS 3.1 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L).

The identified vulnerability resides within the Oracle WebCenter Sites component of the Oracle Fusion Middleware suite, specifically affecting versions 12.2.1.4.0 and 14.1.2.0.0. This security flaw is characterized by its high severity, with a CVSS v3.1 base score of 8.6, indicating significant risk to organizational infrastructure. The vulnerability allows for exploitation by an unauthenticated attacker who requires only network access via the HTTP protocol. Unlike vulnerabilities that require user interaction or complex authentication bypasses, this issue can be triggered remotely without prior credentials, making it particularly dangerous in internet-facing deployments where WebCenter Sites is exposed to external traffic.
From a technical perspective, the flaw enables unauthorized actors to compromise the integrity and confidentiality of the application data. Successful exploitation leads to unauthorized access to critical data stored within the Oracle WebCenter Sites environment. Furthermore, the attacker gains the ability to perform unauthorized update, insert, or delete operations on accessible data sets. This level of control over data manipulation suggests a potential injection-based flaw or improper authorization checks that allow remote code execution or direct database interaction through web requests. The vulnerability also impacts availability, as successful attacks can cause a partial denial of service, disrupting normal business operations and degrading the performance of the WebCenter Sites platform for legitimate users.
The operational impact of this vulnerability is substantial due to its broad scope. An attacker with network access can exfiltrate sensitive information, alter content integrity by modifying or deleting records, and disrupt service availability. This aligns closely with CWE-287 Improper Authentication and CWE-918 SQL Injection if the underlying mechanism involves database query manipulation, though the specific vector is not detailed in the advisory. The ability to cause a partial denial of service indicates that resource exhaustion or application crashes can be induced through malicious requests, further compounding the risk to system stability.
In terms of threat modeling and industry standards, this vulnerability maps to MITRE ATT&CK techniques related to Initial Access via web services and potentially Persistence if data modification allows for backdoor installation. The lack of authentication requirement places it in a high-risk category similar to CVEs involving exposed administrative interfaces or unpatched input validation flaws. Organizations running the affected versions must treat this as a critical priority for remediation due to the ease of exploitation and the comprehensive impact on confidentiality, integrity, and availability.
Mitigation strategies should focus primarily on applying the latest security patches provided by Oracle for WebCenter Sites version 12.2.1.4.0 and 14.1.2.0.0. Until patching is feasible, organizations should implement strict network segmentation to ensure that only trusted internal networks can access the WebCenter Sites application interfaces. Additionally, deploying a web application firewall with rules tuned to detect common injection patterns or anomalous HTTP request behaviors may help mitigate exploitation attempts by blocking malicious payloads before they reach the vulnerable component. Regular monitoring of system logs for unauthorized data modifications and unusual spikes in resource usage is also recommended to detect potential compromise early.
