CVE-2018-17175 (opens in a new tab)How to fix?
Upgrade Debian:14 python-marshmallow to version 3.0.0b14-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-marshmallow package and not the python-marshmallow package as distributed by Debian.
See How to fix? for Debian:14 relevant fixed versions and status.
In the marshmallow library before 2.15.1 and 3.x before 3.0.0b9 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").
