CVE-2026-96677 Details
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.
A cross-site scripting vulnerability has been identified in Apache Juneau versions through 9.2.0. The issue arises in the HTML document serialization process, where variable substitutions are not properly HTML-encoded in the page chrome, including header, nav, aside, footer, and similar fields. This flaw allows applications that incorporate request-derived variables, such as headers, form data, or path values, to reflect those values unencoded, creating an opportunity for cross-site scripting. While the default chrome does not use request variables, applications that add them are vulnerable.
Users are advised to upgrade to Apache Juneau version 9.2.1, which addresses this vulnerability by HTML-encoding substitutions in the HTML chrome and leaving request variables unresolved in script and style fields. If an immediate upgrade is not possible, request variables should be removed from HtmlDocConfig chrome fields.
