Vulnerabilities have been identified in OpenJDK versions 8, 11, and 21, as well as CRaC JDK 21. The RMI component in these versions allows unauthenticated remote attackers to establish TCP endpoint connections without proper endpoint identification, potentially leading to sensitive information theft.
