Summary
Sign-up through an invite link does not properly restrict users from signing up as privileged accounts.
Details
If a user is given an email sign-up link they can potentially create an admin account given certain preconditions. If the default datahub user has been removed, then the user can sign up for an account that leverages the default policies giving admin privileges to the datahub user.
PoC
Given an invite link, sign up for an account with datahub as the username. If default permissions have not also been removed then the newly signed up account has admin privileges.
Impact
All DataHub instances prior to the patch that have removed the datahub user, but not the default policies applying to that user.
