Description Ronit Dey 2026-10-07 10:39:32 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
