I have a custom html form to collect data to put into an SP Custom list. In the form are several text inputs. When using JSOM to add the item to the list, is there server side code to prevent XSS in the text inputs?
I do not have access to the server side to work with submitted data.
I could try some kind of client side JS escape function to try to prevent XSS before submitting but my research seems to indicate clients side validation can be usurped.
