How to fix?

Upgrade org.apache.wicket:wicket-core to version 7.17.0, 8.9.0, 9.0.0 or higher.


org.apache.wicket:wicket-core is a Java web application framework that takes simplicity, separation of concerns and ease of development to a whole new level. Wicket pages can be mocked up, previewed and later revised using standard WYSIWYG HTML design tools. Dynamic content processing and form handling is all handled in Java code using a first-class component model backed by POJO data beans that can easily be persisted using your favorite technology.

Affected versions of this package are vulnerable to Information Disclosure. By crafting a special URL it is possible to make Wicket deliver unprocessed HTML templates. This would allow an attacker to see possibly sensitive information inside a HTML template that is usually removed during rendering.
