  "description": "In the marshmallow library before 2.15.1 and 3.x before 3.0.0b9 for Python, the schema \u0022only\u0022 option treats an empty list as implying no \u0022only\u0022 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 \u0022only\u0022 option, and there is a user role that produces an empty value for \u0022only\u0022).",
