Rclone: Unauthenticated command execution in `rclone rcd –rc-serve` via inline remote instantiation, bypassing CVE-2026-41179 fix_CVE-2026-49980

{
    "lastseen": "",
    "description": "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.",
