Description
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.74.4, with -l/--links, rclone serializes symlinks as .rclonelink text objects and recreates them on a local destination without validating the target, allowing an attacker-controlled remote to plant an escaping symlink and cause a following object write to land outside the destination with attacker-chosen contents. This issue is fixed in version 1.74.4.
