CVE-2025-55748: XWiki configuration files can be accessed through jsx and sx endpoints

September 3, 2025

It’s possible to get access and read configuration files by using URLs such as http://localhost:8080/bin/ssx/Main/WebHome?resource=../../WEB-INF/xwiki.cfg&minify=false.

This can apparently be reproduced on Tomcat instances.
