For example if you use the following payload: ” accesskey=”x” onclick=”alert(1)” x=”, the content will be saved within the database without any control. And then once you return to the summary documents page, by clicking on the “Web Link” of the newly created file it will create a new empty tab, but on the initial tab the pop-up “1” will appear.
