Root.Mkdir(All) can follow junctions out of the root on Windows in os
Quick fix
GO-2026-6604 — stdlib: upgrade to the fixed version with the command below.
go get stdlib@v1.26.9Details
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).
