CVE-2026-83067 in JDeveloper
Summary
by MITRE • 09/16/2026
Vulnerability in the Oracle JDeveloper product of Oracle Fusion Middleware (component: ADF Shared Components). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle JDeveloper. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle JDeveloper accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle JDeveloper. CVSS 3.1 Base Score 8.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).

The identified vulnerability resides within the ADF Shared Components of Oracle JDeveloper, a critical development tool included in the Oracle Fusion Middleware suite. This security flaw affects specific supported versions, namely 12.2.1.4.0 and 14.1.2.0.0, exposing developers to significant risks during the application design and coding phases. The core of the issue lies in how these shared components handle input data processed over HTTP connections. Because Oracle JDeveloper is often used as an integrated development environment where users load various project files and configurations, any weakness in parsing or validating this input can be leveraged by malicious actors to disrupt operations or manipulate system state.
From a technical perspective, the vulnerability allows for exploitation by low-privileged attackers who possess network access via HTTP. This indicates that the flaw does not require authentication or elevated privileges on the target machine, significantly lowering the barrier to entry for potential adversaries. The attack vector is remote and requires no user interaction beyond establishing an HTTP connection, which makes it particularly dangerous in environments where JDeveloper might be exposed to internal networks or potentially external interfaces if misconfigured. The absence of a requirement for UI interaction means that automated tools can easily probe and exploit this weakness without needing complex social engineering tactics.
The operational impact of successfully exploiting this vulnerability is severe, characterized by high integrity and availability impacts as reflected in the CVSS 3.1 base score of 8.1. Attackers who compromise Oracle JDeveloper through this flaw gain the ability to perform unauthorized creation, deletion, or modification of critical data. This directly compromises the confidentiality and integrity of sensitive information stored within the development environment, including source code, configuration files, database credentials, and proprietary algorithms. Furthermore, the vulnerability enables attackers to cause a hang or frequently repeatable crash of the application, leading to a complete denial of service. For developers relying on JDeveloper for continuous integration or rapid prototyping, such instability can result in significant productivity losses and potential data corruption if unsaved work is lost during crashes.
This incident aligns with common vulnerability classifications found in industry standards. The ability to cause unauthorized modification of data points towards CWE-94 Improper Control of Generation of Code (Code Injection) or CWE-78 OS Command Injection, depending on the specific mechanism exploited within the ADF components. The resulting denial of service conditions are consistent with CWE-400 Uncontrolled Resource Consumption or CWE-611 XML External Entity injection if the flaw involves parsing external resources. In terms of adversary tactics, this vulnerability facilitates actions described in MITRE ATT&CK framework under techniques such as T1537 Transfer Data to Cloud Account for Exfiltration if data is stolen, or more directly T1499 Endpoint Denial of Service through application crashes and resource exhaustion.
Mitigation strategies must focus on immediate patching and network segmentation. Oracle has likely released patches addressing this specific flaw in the ADF Shared Components; therefore, administrators should prioritize updating affected versions to the latest security-fixed releases provided by Oracle. Until patches are applied, organizations should restrict access to JDeveloper instances strictly to trusted internal networks using firewalls or reverse proxies that enforce strict input validation and rate limiting on HTTP requests. Additionally, running JDeveloper with minimal necessary privileges can help contain the blast radius of a potential compromise, ensuring that even if an attacker exploits this vulnerability, their ability to modify critical system data is limited by operating system permissions. Regular security audits and static code analysis tools should also be employed to detect any residual risks in custom ADF applications developed using these vulnerable components.
