Summary

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, rclone archive extract can write extracted files outside the user-selected destination prefix when extracting a crafted archive containing parent path components such as ../, allowing creation or overwrite of sibling objects in the same bucket or path scope. This issue is fixed in version 1.74.4.
