Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, rclone serve restic --private-repos enforces authorization using the routed user path segment while building the backend object key from the raw uncleaned URL path, allowing an authenticated user to include .. in a request such as //..//config and read, overwrite, or delete another user's private repository on backends that clean path components. This issue is fixed in version 1.74.4.
