### Summary If a user is granted the `admin:users` scope, they may escalate their own privileges by making themselves a full admin user. ### Details The `admin:users` scope allows a user to edit user records: > admin:users > > Read, write, create and delete users and their authentication state, not including their servers or tokens. > > -- https://jupyterhub.readthedocs.io/en/stable/rbac/scopes.html#available-scopes However, this includes making users admins. Admin users are granted scopes beyond `admin:users` making this a mechanism by which granted scopes may be escalated. ### Impact The impact is relatively small in that `admin:users` is already an extremely privileged scope only granted to trusted users. In effect, `admin:users` is equivalent to `admin=True`, which is not intended. Note that the change here only prevents escalation to the built-in JupyterHub admin role that has unrestricted permissions. It does not prevent users with e.g. `groups` permissions from granting ...

Researchers at Aqua Security discovered the "Shadow Resource" attack vector and the "Bucket Monopoly" problem, where threat actors can guess the name of S3 buckets based on their public account IDs.
The last few years have seen more than a few new categories of security solutions arise in hopes of stemming a never-ending tidal wave of risks. One of these categories is Automated Security Validation (ASV), which provides the attacker’s perspective of exposures and equips security teams to continuously validate exposures, security measures, and remediation at scale. ASV is an important element
Hacker Samy Kamkar is debuting his own open source version of a laser microphone—a spy tool that can invisibly pick up the sounds inside your home through a window, and even the text you’re typing.
