CVE-2026-47030: Low severity Oracle Java SE (JavaFX) vulnerability
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).
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Upgrade
Upgrade
Oracle Java SE (JavaFX)to a version that resolves this vulnerability.Fixed in 8u491 - Compensating control
Apply compensating mitigation by ensuring affected Java deployments only load and run trusted code (code installed by an administrator), since the described vulnerability applies to Java deployments that load and run untrusted code and rely on the Java sandbox.
- Operational
Because successful attacks require human interaction from a person other than the attacker, reduce exposure by preventing users from running untrusted Java Web Start applications or sandboxed Java applets that load code from the internet.
