Upgrade org.apache.jspwiki:jspwiki-main to version 2.12.4-RC2 or higher.
Overview
org.apache.jspwiki:jspwiki-main is a main release jar for Apache JSPWiki engine.
Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) through the AJAXPreview.jsp preview handler in jspwiki-war/src/main/webapp/templates/default/AJAXPreview.jsp and its caller in jspwiki-war/src/main/scripts/jspwiki-edit.js. An attacker can force a victim’s browser to issue a cross-site preview request by sending a crafted GET request to the AJAX preview endpoint, causing the application to process editable wiki markup without CSRF protection. This can expose or manipulate previewed page content in the user’s session and let an attacker drive unwanted edit-related actions from the victim’s browser. As a result, users can be tricked into performing preview requests that the application treats as part of an edit workflow.
