Published Oct 20, 2026 CVSS 3.1 · 3.1 Low EPSS < 1% KEV · Not listed
Description
Vulnerability in the Oracle JavaFX product of Oracle Java SE (component: JavaFX). Supported versions that are affected are Oracle JavaFX: 25.0.4 and 27. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle JavaFX. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle JavaFX 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.
