The CVE record names the fixed release — apply it.

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

This issue affects Apache Commons BCEL: before 6.13.0.

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