## Overview

Symbolic name not mapping to correct object vulnerability in Apache Commons.



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: before 6.13.0.



Users are recommended to upgrade to version 6.13.0, which fixes the issue.
