Summary
In the marshmallow library before 2.15.1 for Python, the schema "only"
option treats an empty list as implying no "only" option, which allows a
request that was intended to expose no fields to instead expose all fields
(if the schema is being filtered dynamically using the "only" option, and
there is a user role that produces an empty value for "only")
(CVE-2018-17175).
