Improper access to parent directory of root in os
Quick fix
GO-2026-4403 — stdlib: upgrade to the fixed version with the command below.
go get stdlib@v1.23.9Details
It was possible to improperly access the parent directory of an os.Root by opening a filename ending in "../". For example, Root.Open("../") would open the parent directory of the Root. This escape only permits opening the parent directory itself, not ancestors of the parent or files contained within the parent.
