Description An unauthenticated attacker with network access via multiple protocols can compromise the system. This issue exists within the Libraries component and can be exploited through APIs, such as web services that provide data to these APIs. It also affects Java deployments that load and run untrusted code, such as sandboxed Java Web Start applications or sandboxed Java applets, which rely on the Java sandbox for security. Successful exploitation may lead to unauthorized creation, deletion, or modification of critical data or all accessible data.

Recommendations Update Oracle Java SE to versions 8u491, 11.0.32, 17.0.20, 21.0.12, 25.0.4, or 26.0.2. Update Oracle GraalVM for JDK to versions 17.0.20 or 21.0.12. Update Oracle GraalVM Enterprise Edition to a version newer than 21.3.18.
