Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Rclone versions before 1.74.4 are vulnerable when run with `-l/--links` against a local destination. Symlink targets taken from an untrusted remote are not validated, so an attacker controlling that remote can make rclone create symlinks pointing anywhere on the victim's filesystem and write files through them, potentially overwriting files such as shell rc files or authorized_keys. Upgrade to rclone 1.74.4 or later. Avoid using `-l/--links` when syncing from remotes you do not trust.
