Apollo Federation has Improper Enforcement of Access Control on Transitive Fields
# Summary
A vulnerability in Apollo Federation's composition logic did not enforce that fields depending on protected data through `@requires` and/or `@fromContext` directives have the same access control requirements as the fields they reference. This allowed queries to access protected fields indirectly through their dependencies, bypassing access control checks. A fix to composition logic in Federation now enforces that dependent fields match the access control requirements from of the fields they reference.

@apollo/composition has Improper Enforcement of Access Control on Interface Types and Fields
Apollo Federation is an architecture for declaratively composing APIs into a unified graph. A vulnerability in versions of Apollo Federation's composition logic prior to 2.9.5, 2.10.4, 2.11.5, and 2.12.1 allowed some queries to Apollo Router to improperly bypass access controls on types/fields. Apollo Federation incorrectly allowed user-defined access control directives on interface types/fields, which could be bypassed by instead querying the implementing object types/fields in Apollo Router via inline fragments, for example. A fix to versions 2.9.5, 2.10.4, 2.11.5, and 2.12.1 of composition logic in Federation now disallows interfaces types
