JavaFX Remote Code Execution via Network Protocols

Publication date: 2026-07-21

Last updated on: 2026-08-03

Assigner: Oracle

Description

Vulnerability in Oracle Java SE (component: JavaFX). The supported version that is affected is Oracle Java SE: 8u491. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.1 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N).

Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Java SE, specifically in the JavaFX component. It affects version 8u491 and allows an unauthenticated attacker to potentially modify data in Oracle Java SE through network access. Exploitation requires user interaction and is difficult to perform.

Detection Guidance

This vulnerability affects Oracle Java SE 8u491, specifically JavaFX deployments running untrusted code. Detection involves checking Java versions and JavaFX usage. Use commands like 'java -version' to verify Java SE version and 'where java' or 'which java' to locate installations. Inspect running Java processes with 'jps -l' or 'ps aux | grep java' to identify JavaFX applications.

Impact Analysis

If you use Java applications that load untrusted code from the internet, this vulnerability could allow an attacker to modify data within those applications. This is most relevant for clients running sandboxed Java Web Start or applets, not server-side deployments.

Compliance Impact

This vulnerability allows unauthorized modification of data, which could impact integrity controls required by GDPR and HIPAA. However, the low CVSS score and requirement for human interaction limit its real-world compliance risk.

Mitigation Strategies

Immediately upgrade Oracle Java SE to a version beyond 8u491. Disable JavaFX in client deployments if not required. Restrict Java applets and Web Start applications from loading untrusted code. Apply network-level controls to block unnecessary protocols used by Java. Monitor for unusual Java processes or network activity.
