Penpot is an open-source design and prototyping platform. Prior to 2.18.0, create-team-invitations and the invitation acceptance path allow a non-owner team administrator to assign the owner role because invitation roles are persisted and applied without the role-ceiling check used by update-team-member-role. An administrator can invite another account as an owner, create multiple owners, and then use the new owner account to obtain owner-only control over the team. This issue is fixed in version 2.18.0.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
