Published Oct 20, 2026
·
Updated

Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Networking). Supported versions that are affected are Oracle Java SE: 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, 27; Oracle GraalVM for JDK: 17.0.20.1 and 21.0.12.1; 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 for JDK, 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 for JDK, 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 deployments are most exposed to this issue?

Exposure includes applications or web services that pass network-supplied data into the affected Networking APIs. Java client deployments running sandboxed Java Web Start applications or sandboxed applets that load untrusted internet-originated code and rely on the Java sandbox are also affected.

2

What does an attacker need to exploit the vulnerability?

An unauthenticated attacker needs network access through multiple protocols and must overcome high attack complexity. Exploitation may occur through a web service that supplies data to APIs in the affected component.

3

What could a successful attack allow?

A successful attack can allow unauthorized update, insert, or delete operations on some data accessible to the affected Oracle Java SE or GraalVM product.

4

Which versions are identified as affected?

Affected Oracle Java SE versions are 8u503, 8u503-perf, 11.0.32.1, 17.0.20.1, 21.0.12.1, 25.0.4.1, and 27. Affected Oracle GraalVM for JDK versions are 17.0.20.1 and 21.0.12.1; Oracle GraalVM Enterprise Edition 21.3.19.1.1 is also affected.
