/**
|
||
|
|
* Regression guard for a live privilege escalation.
|
||
|
|
*
|
||
|
|
* The built-in `users` collection ships with createRule "" (anyone may sign
|
||
|
|
* up) and updateRule "id = @request.auth.id" (anyone may edit themselves).
|
||
|
|
* Because `role` is an ordinary field on that collection, both were
|
||
|
|
* exploitable: an anonymous request could create an owner account, and a
|
||
|
|
* client manager could promote themselves to owner and then read every other
|
||
|
|
* client's board. Both were verified working against the live instance before
|
||
|
|
* the rules were locked.
|
||
|
|
*
|
||
|
|
* If either test here fails, someone has reverted the users rules and every
|
||
|
|
* client's data is readable by anyone who can reach the PocketBase URL.
