Rclone: Unauthenticated command execution in `rclone rcd --rc-serve` via inline remote instantiation, bypassing CVE-2026-41179 fix

Rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.46.0 until 1.74.3, rclone rcd --rc-serve accepts unauthenticated GET and HEAD requests to paths of the form: /[remote:path]/object. The remote value is parsed from the URL and passed to normal backend initialization. Inline remote configuration can set backend options that execute local commands during initialization. As a result, a single unauthenticated GET or HEAD request can execute a command as the rclone process user. This vulnerability is fixed in 1.74.3.

Is like Dropbox sync client but for more than 30 services, adds an indicator to the top panel so you can manage the rclone profiles configured in your system, perform operations such as mount as remote, watch for file modifications, sync with remote storage, navigate it's main folder. Also, it shows the status of each profile so you can supervise the operations, and provides an easy access log of events. Backup and restore the rclone configuration file, so you won't have to configure all your devices one by one
