Information Exposure

Affecting marshmallow package, versions [,2.15.1), [3.0.0,3.0.0b9)

Overview

marshmallow is an ORM/ODM/framework-agnostic library for converting complex datatypes, such as objects, to and from native Python datatypes.

Affected versions of this package are vulnerable to Information Exposure. 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.

Remediation

Upgrade marshmallow to version 2.15.1, 3.0.0b9
