## Description

Sharetribe Go is a source available marketplace software. In affected versions operating system command injection is possible on installations of Sharetribe Go, that do not have a secret AWS Simple Notification Service (SNS) notification token configured via the `sns_notification_token` configuration parameter. This configuration parameter is unset by default. The vulnerability has been patched in version 10.2.1. Users who are unable to upgrade should set the`sns_notification_token` configuration parameter to a secret value.
