Well it is a universally unique identifier not secret. There's no ensurance of it being random unless you're generating v4 UUIDs.

And even if you are generating v4 UUIDs, they are not necessarily cryptographically secure. So it might be possible, if lets say, a user gets a bunch of UUIDs that your system generated, it might be possible for they to figure out other UUIDs that the same system generated. Which is totally fine for what they were built for.
