CVE-2021-28167: Eclipse OPENJ9

Medium severity, CVSS 6.5. EPSS: 1.1% chance of exploitation in the next 30 days.

In Eclipse Openj9 to version 0.25.0, usage of the jdk.internal.reflect.ConstantPool API causes the JVM in some cases to pre-resolve certain constant pool entries. This allows a user to call static methods or access static members without running the class initialization method, and may allow a user to observe uninitialized values.

Affected products

• Eclipse OPENJ9: up to and including 0.25.0
