CVE
CVE-2026-41179
Unauthenticated backend instantiation in github.com/rclone/rclone
The operations/fsinfo remote control (RC) endpoint in rclone was registered without requiring authentication. This allowed unauthenticated callers to instantiate arbitrary backends via inline backend definitions, which could lead to local command execution if the backend configuration allows it (e.g., via bearertokencommand in webdav or ssh in sftp).
