NVD Description

Note: Versions mentioned in the description apply only to the upstream objenesis-javadoc package and not the objenesis-javadoc package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

Objenesis before 3.6 contains a type confusion vulnerability that allows code in one class loader to substitute objects into another by exploiting instantiator caching keyed on class name. When a shared ObjenesisStd instance caches instantiators by clazz.getName() in ObjenesisBase.getInstantiatorOf(), same-named classes collide, causing newInstance() to return wrong-class objects and ClassCastException failures.
