NVD Description

Note: Versions mentioned in the description apply only to the upstream unoserver-rest-api package and not the unoserver-rest-api package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

On Windows, when the target of Root.Mkdir or Root.MkdirAll is a junction pointing to an empty location, the operation can create a directory at the junction target even when that target is located outside the root. This only applies to operations where the last path component is a junction (path/to/junction, but not path/junction/target).
