Term	Kind	Topic	What it is
Administrative Path Blindness Support Tool Gap, Internal Access Blind Spot	concept	Authorization	The pattern where the customer-facing data path is rigorously access-controlled while internal dashboards, support tools, analytics jobs and exports have unrestricted access - protecting against the wrong adversary.
Confused Deputy	concept	Authorization	A privileged component tricked into performing an action on behalf of a caller who lacks the authority to perform it directly.
Object-Level Authorization BOLA, IDOR	concept	Authorization	Checking that the caller is entitled to the specific record they requested, not merely that they may call the endpoint.
Relationship-Based Access Control ReBAC, Graph Authorization	concept	Authorization	Expressing permissions as relationships between subjects and objects, with inheritance and group expansion as rules over the graph, rather than as attributes on rows.
Role Explosion	concept	Authorization	The proliferation of narrowly-scoped roles that occurs when RBAC is used to express rules that actually depend on context.
