No, this does actually sound like a solution. But it’s a solution that should be scattered all throughout the process, and checked at multiple steps along the way. The fact that this wasn’t here to begin with is a bigger problem than the “client library failure” as it shows Wyze’s security practices are fucking garbage. And adding “one layer” is not enough. There should be several.

To give a bit better context, which I can only be guessing at by reading between the lines of their vague descriptions and my first hand experience with these types of systems…

Essentially your devices all have unique ids. And your account has an account/user ID. They’re essentially “random numbers” that are unique within each set, but there appear to be devices that have the same ID as a some user’s user ID.

When the app wants to query for video feeds it’s going to ask the server “hey, get me the feed for devices A, B, and C. And my user ID is X”. The server should receive this, check if that user has access to those devices. But that server is just the first external facing step. It then likely delegates the request through multiple internal services which go look up the feed for those device IDs and return them.

The problem that happened is somewhere in there, they had an “oopsie” and they passed along “get me device X, X, X for user ID X”. And for whatever reason, all the remaining steps were like “yup, device X for user X, here you go”. At MULTIPLE points along that chain, they should be rechecking this and saying “woah, user X only has access to devices A, B, and C, not X. Access denied.”

The fact that they checked this ZERO times, and now adding “a layer” of verification is a huge issue imo. This should never have been running in production without multiple steps in the chain validating this. Otherwise, they’re prone to both bugs and hacks.

But no, they clearly weren’t verified to view the events. Their description implies that somewhere in the chain they scrambled what was being requested and there were no further verifications after that point. Which is a massive issue.
