    How secure is the edit link of the submission?

    Asked by Jon Eckstein  on November 10, 2016 at 02:25 AM

    Hi JotForms,

    I've been playing with the v4 builder and really liking it!  I've been looking for a service that allows the user to go back and view/edit their answers at a later date as I'm building a fairly complicated form flow with multiple pages and multiple forms.  

    My question is the following:

    I understand how the edit links work and I was able to get it working within an iframe which is great, but I'm a little worried about the edit links themselves.  How secure are they?

    If I'm a hacker and I want to get someone's jotform answers couldn't I just get lucky by entering the edit url in a browser:


    where <some_random_number> is some random number that gets filled in via a script?

    I hope that's clear, thanks for any help.

    Thank you for the feedback about the new form builder.

    As for the Edit URL, the numbers are open and if one can guess it, they should be able to get the data on the form. But I don't think someone should be able to guess the number considering its length. If that really matters to you, I'll be happy to send this to our backend team. Let me know.

    It's not a matter of a human guessing it, it's a matter of someone writing
    a script that runs through a trillion numbers and gets it.
    Yes, please send to the backend team as I'm wondering if there's an added
    layer of security that can be put in place like requiring a header with a
    client key or something similar.

    Hi Owen,
    Are there any updates on this issue? I would really love to implement an
    embedded Jotform solution into an app I'm working with. But the risk of
    data exposure with the current edit endpoints isn't workable, I'll be
    dealing with a lot of sensitive data.
    Thanks for any help.
