AI-suggested
Upgrade Rclone to version 1.73.5 or later, where this vulnerability is patched. Additionally, ensure that the RC server is not exposed without authentication; enable authentication for the RC server if it must be used. If upgrading immediately is not possible, restrict network access to the RC server to trusted hosts only.
Description
Rclone versions from 1.48.0 up to but not including 1.73.5 contain a critical vulnerability in the Remote Control (RC) endpoint operations/fsinfo. This endpoint is exposed without authentication and accepts attacker-controlled input that allows instantiation of malicious backends. Specifically, the WebDAV backend executes a command during initialization, enabling unauthenticated local command execution on deployments where the RC server is running without authentication. The issue is patched in version 1.73.5.
