Published Oct 20, 2026
·
Updated

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 8u503 and 8u503-perf; Oracle GraalVM Enterprise Edition: 21.3.19.1.1. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also 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. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).

Frequently Asked Questions

1

Which environments are most exposed to this issue?

Deployments that expose the affected 2D APIs through network-accessible services, such as web services that supply data to those APIs, are exposed. Client deployments running sandboxed Java Web Start applications or sandboxed Java applets that load untrusted internet-supplied code and rely on the Java sandbox are also affected.

2

Does exploitation require authentication or user interaction?

No authentication or user interaction is required. However, exploitation is described as difficult and requires network access through multiple protocols.

3

What could a successful attacker do?

A successful attack can provide unauthorized update, insert, or delete access to some data accessible to the affected Java SE or GraalVM Enterprise Edition deployment. The stated impact is limited to integrity; no confidentiality or availability impact is specified.
