Description The issue allows remote attackers to inject arbitrary web script or HTML via the calid or paletteDefault parameter in an editevent action to "index.php".

Recommendations For versions 4.0.2 through 4.8.5, avoid using the calid and paletteDefault parameters in the editevent action to index.php until a fix is available. As a temporary workaround, consider restricting access to the tmpl/layout editevent.php file to minimize the risk of exploitation.
