A website hosts private/personal information at a very long and unpredictable URI, yet access to this URI is completely unauthenticated. Are there any major security issues with this?
I can think of some straight away:
- Search engines might index the information if the link ever appears anywhere on the web
- It would be trivial to access the information by simply looking at someone's screen and remembering/taking a photo of the URI
- Alike to the above, the data would also be very accessible from the user's browsing history
- Depending on various factors, the URI might be brute-forced eventually
Are there any others?
