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.
