Overview
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 Cross-site Request Forgery (CSRF) in FetchMetadataResourceIsolationPolicy and ResourceIsolationRequestCycleListener in the wicket-core HTTP request cycle. An attacker can invoke a victim’s authenticated listener action by sending the browser to a listener URL from another site or from a sibling origin on the same site. The vulnerable policy treated Sec-Fetch-Site: same-site as allowed and did not distinguish a page render from a listener invocation, so cross-site top-level GET navigations and same-site requests could reach Link.onClick(), form submits, and similar callbacks. This lets an attacker trigger unintended actions in the victim’s session, causing state-changing requests to run as the user.
