Description Ronit Dey 2026-10-07 09:12:18 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.

Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Apache Commons BCEL.



This only happens when you're using Class2HTML to generate webpages for possibly-attacker-controlled class files, where Class2HTML emitters write attacker class-file strings into HTML unescaped (stored XSS in reports).



This issue affects Apache Commons BCEL: before 6.13.0.



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

At least nokogiri on Fedora does not ship jruby so this is unrelated at the first time.
