| Doc Text: |
A path traversal vulnerability has been identified in the Go os package affecting the Root abstraction, where improper handling of trailing path separators could allow access to the parent directory of a configured root directory. By supplying a filename ending in "../", an attacker may be able to open the immediate parent directory of the intended Root. Although this escape does not allow traversal to higher-level ancestors or direct access to files within the parent directory, it may expose directory metadata or unintended filesystem structure if the application passes untrusted path input to Root.Open.

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.
