CWE
- CWE-386 - Symbolic Name not Mapping to Correct Object
Summary
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.

CWE
- CWE-386 - Symbolic name not mapping to correct object
Summary
Symbolic name not mapping to correct class.
BCEL caches attacker-controlled classes under their self-declared names without validating the requested name, allowing subsequent lookups and name-keyed verification results to refer to a different class.
This issue affects Apache Commons BCEL: before 6.13.0.
Users are recommended to upgrade to version 6.13.0, which fixes the issue.
