CVE-2026-116486

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...

CVE-2026-116486

The Objenesis library, in versions before 3.6 , is susceptible to a type confusion vulnerability. The root cause is an instantiator caching flaw where a shared ObjenesisStd instance uses clazz.getName() as a key in ObjenesisBase.getInstantiatorOf(). This allows classes with the same name but diff...

[SECURITY] Fedora 40 Update: objenesis-3.3-9.fc40

Objenesis is a small Java library that serves one purpose: to instantiate a new object of a particular class. Java supports dynamic instantiation of classes using Class.newInstance; however, this only works if the class has an appropriate constructor. There are many times when a class cannot be...
