CVE-2026-60354 Overview
CVE-2026-60354 is an information disclosure vulnerability in the Oracle JDeveloper product of Oracle Fusion Middleware. The flaw resides in the Data Visualization Tools component and affects supported versions 12.2.1.4.0 and 14.1.2.0.0. An unauthenticated attacker with network access via HTTP can exploit this vulnerability to obtain unauthorized read access to a subset of Oracle JDeveloper accessible data. Exploitation is rated as difficult, and the vulnerability impacts only confidentiality, with no integrity or availability effects. Oracle disclosed the issue in the Oracle Critical Patch Update Advisory for July 2026.
Critical Impact
Successful exploitation grants an unauthenticated remote attacker read access to a limited subset of Oracle JDeveloper data over HTTP.
Affected Products
- Oracle JDeveloper 12.2.1.4.0
- Oracle JDeveloper 14.1.2.0.0
- Oracle Fusion Middleware — Data Visualization Tools component

Technical Details for CVE-2026-60354
Vulnerability Analysis
The vulnerability affects the Data Visualization Tools component of Oracle JDeveloper, part of Oracle Fusion Middleware. An unauthenticated remote attacker can craft HTTP requests to the affected component and retrieve a limited subset of data accessible to JDeveloper. The issue is classified as an information disclosure weakness because it impacts confidentiality only, without altering data or affecting availability.
Oracle notes that exploitation is difficult, indicating conditions beyond the attacker's control must be met for the attack to succeed. Such conditions typically involve specific configurations, timing dependencies, or reliance on intermediate systems. The EPSS probability for this CVE is 0.258%, reflecting a low predicted likelihood of exploitation in the near term.
No public proof-of-concept, exploit code, or CISA Known Exploited Vulnerabilities listing exists for this issue at publication.
Root Cause
Oracle's advisory does not disclose the underlying code defect. The vulnerability resides in server-side handling within the Data Visualization Tools component and permits reading data without authentication. Root-cause details will remain limited to Oracle's advisory content until further technical analysis is released.
Attack Vector
The attack vector is network-based over HTTP. An attacker sends crafted requests to a reachable JDeveloper instance exposing the Data Visualization Tools component. No credentials and no user interaction are required. Because the attack complexity is high, an attacker must satisfy additional preconditions to achieve information disclosure. Successful exploitation returns a subset of data accessible to the JDeveloper process to the attacker.
No verified exploitation code is publicly available. Refer to the Oracle Security Alert July 2026 for authoritative technical details.
Detection Methods for CVE-2026-60354
Indicators of Compromise
- Unexpected HTTP requests to Oracle JDeveloper endpoints associated with Data Visualization Tools from unauthenticated or untrusted sources.
- Anomalous outbound data volumes from JDeveloper hosts that suggest bulk read access.
- Access log entries showing repeated probing of JDeveloper URLs without corresponding authentication events.
Detection Strategies
- Enable verbose HTTP access logging on Oracle Fusion Middleware and forward logs to a centralized analytics platform for correlation.
- Baseline normal request patterns against JDeveloper components and alert on deviations, particularly unauthenticated access to Data Visualization endpoints.
- Deploy web application firewall (WAF) rules that flag suspicious request patterns targeting JDeveloper Data Visualization Tools.
Monitoring Recommendations
- Monitor JDeveloper server processes for unusual read activity, file access, or data serialization events.
- Track authentication failures alongside successful data-returning responses to identify unauthenticated data retrieval.
- Alert on network flows to JDeveloper hosts originating from outside expected administrative or developer networks.
How to Mitigate CVE-2026-60354
Immediate Actions Required
- Apply the Oracle Critical Patch Update for July 2026 to all Oracle JDeveloper 12.2.1.4.0 and 14.1.2.0.0 installations.
- Inventory Oracle Fusion Middleware deployments to identify systems exposing the Data Visualization Tools component.
- Restrict network access to JDeveloper instances to trusted administrative networks only until patching is complete.
Patch Information
Oracle addressed CVE-2026-60354 in the July 2026 Critical Patch Update. Administrators should download and apply the relevant patches referenced in the Oracle Security Alert July 2026. Verify patch application against Oracle's inventory tooling and validate that the affected component version is updated.
Workarounds
- Place JDeveloper instances behind an authenticated reverse proxy to prevent unauthenticated HTTP requests from reaching the Data Visualization Tools component.
- Apply network segmentation and firewall rules to block untrusted HTTP access to Oracle Fusion Middleware hosts.
- Disable or restrict the Data Visualization Tools component in production environments where it is not required.
