The documentation states the flag \"can be used to limit users to repositories starting with a path of `//`\", and the shipped test `TestResticPrivateRepositories` asserts that user `test` may reach `/test/config` but is `403`-blocked from `/other_user/config`. This isolation is the entire security purpose of the flag.\n\nThe isolation is enforced by two independent chi middlewares that derive the username and the backend object path from two *different* sources, and the path source is never canonicalized. `checkPrivate` authorizes the request by comparing the routed `{userID}` path segment against the authenticated user, while `WithRemote` builds the backend object key from the raw, un-cleaned URL path. A request such as `GET //..//config` keeps the first path segment equal to the attacker's own username (so `checkPrivate` returns the request as authorized) yet hands the backend the literal remote `me/../victim/config`.
