What it is

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.
