Summary
Apache Commons BCEL before 6.13.0 is affected. Its class repositories cache attacker-supplied class files under the names those classes declare, without checking the requested name (CWE-386). A remote attacker who can supply class files can make later name-based lookups and verification results refer to a different class. No authentication or user interaction is needed.

Description from the CNA
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.
