CVE-2024-52522

Summary

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Insecure handling of symlinks with –links and –metadata in rclone while copying to local disk allows unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files, compromising system integrity, confidentiality, and availability. This vulnerability is fixed in 1.68.2.
