Summary

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.

Is CVE-2026-96677 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-96677 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
