Hi everyone, does anyone have enough knowledge on *cfpdf* *action*="sanitize" to say something about it's efficacy in removing scripts, active content etc. from PDF's? I want to read more about it but I am struggling to find any good sources reviewing the functionality.

James, unfortunately, there is not a lot of detail on this other than trial and error. It's equivalent to using the print-to-PDF feature from any third-party application. In Acrobat, you can program and embed javascript and PDF actions such as Saving the content to a server or sending the information to the cloud for some other action; the sanitize function removes that.
