Sources and claim methodology

Upstream source description

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.
