Description

The MStore API plugin for WordPress is vulnerable to arbitrary file uploads due to missing authorization via the api/flutter_woo/config_file REST endpoint in versions before 3.4.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.
