Summary

Vulnerability in the Networking component of Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition. An unauthenticated attacker with network access can perform unauthorized data modification and cause a partial denial of service. The vulnerability also applies to Java deployments running untrusted code in a sandbox.

Risk Assessment

A remote, unauthenticated attacker can modify some data accessible to the Java application and partially disrupt its availability. This may compromise the integrity of processed information and service stability.

Recommendation

Update Oracle Java SE, Oracle GraalVM for JDK and Oracle GraalVM Enterprise Edition to the versions with Oracle's fix. Restrict network access to Java applications processing untrusted data.
