Cross-site scripting in FanCMS 1.0.0 allows remote attackers to execute JavaScript through the content1 parameter in demo.php. The demo.php page renders the parameter without filtering, causing a browser to interpret injected JavaScript in the FanCMS origin. Exploitation requires a user to load the crafted output, exposing data and actions available to that user's session.
