Name of the Vulnerable Software and Affected Versions Oracle Java SE versions 8u431-perf, 11.0.25, 17.0.13, 21.0.5, 23.0.1 Oracle GraalVM for JDK versions 17.0.13, 21.0.5, 23.0.1 Oracle GraalVM Enterprise Edition versions 20.3.16, 21.3.12

Description A difficult to exploit vulnerability allows unauthenticated attackers with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks can result in unauthorized update, insert, or delete access to some accessible data, as well as unauthorized read access to a subset of accessible data. This vulnerability can be exploited by using APIs in the specified component, for example, through a web service that supplies data to the APIs. It also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code and rely on the Java sandbox for security.

Recommendations For Oracle Java SE versions 8u431-perf, 11.0.25, 17.0.13, 21.0.5, 23.0.1, update to a newer version that contains a fix for this vulnerability. For Oracle GraalVM for JDK versions 17.0.13, 21.0.5, 23.0.1, update to a newer version that contains a fix for this vulnerability. For Oracle GraalVM Enterprise Edition versions 20.3.16, 21.3.12, update to a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the vulnerable component until a patch is available. Avoid using APIs in the specified component until the issue is resolved.
