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.

Affected products

• rclone: before 1.74.4 — fixed in 1.74.4

How to fix

Upgrade to a fixed version: rclone 1.74.4. Check the vendor advisory for mitigations.
