Original description

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache Juneau. HTML document serialization does not HTML-encode variable substitutions in the page chrome (header, nav, aside, footer and similar fields). Applications whose chrome includes request-derived variables, such as request headers, form data or path values, reflect those values unencoded, allowing cross-site scripting. The default chrome does not use request variables, so only applications that add them are affected. This issue affects Apache Juneau: through 9.2.0. Users are recommended to upgrade to version 9.2.1, which fixes the issue.
