UBUNTU-CVE-2026-83387: Medium severity ubuntu/openjdk-8 vulnerability
Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JDBC). 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 access to critical data or complete access to all 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 5.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

Frequently Asked Questions
What level of attacker access is required?
An unauthenticated attacker needs network access and must exploit the issue through one of multiple protocols. The vulnerability is rated difficult to exploit.
Which deployment patterns are most relevant for triage?
Prioritize applications that use the affected JDBC APIs, including web services that supply data to those APIs. Also assess client deployments running sandboxed Java Web Start applications or sandboxed Java applets that load untrusted internet-supplied code and rely on the Java sandbox.
What is the potential impact of a successful attack?
A successful attack can provide unauthorized access to critical data or complete access to data accessible to the affected Java SE or GraalVM deployment.
