**Name of the Vulnerable Software and Affected Versions** Oracle Java SE versions 8u421, 8u421-perf, 11.0.24, 17.0.12, 21.0.4, 23 Oracle GraalVM for JDK versions 17.0.12, 21.0.4, 23 Oracle GraalVM Enterprise Edition versions 20.3.15, 21.3.11 **Description** The issue is related to insufficient input validation in the Diagnostics component of the affected products, allowing an unauthenticated attacker with network access via multiple protocols to compromise the system. Successful attacks can result in a partial denial of service (DOS) of the affected products. This issue applies to Java deployments that load and run untrusted code, such as sandboxed Java Web Start applications or sandboxed Java applets, and rely on the Java sandbox for security. **Recommendations** For Oracle Java SE versions 8u421, 8u421-perf, 11.0.24, 17.0.12, 21.0.4, 23, update to a version that includes the fix for this issue. For Oracle GraalVM for JDK versions 17.0.12, 21.0.4, 23, update to a version that includes the fix for this issue. For Oracle GraalVM Enterprise Edition versions 20.3.15, 21.3.11, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the Diagnostics component until a patch is available.
