Echo: rclone: security update to 1.75.1

medium Tenable Cloud Security Plugin ID 478383

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - rclone versions 1.56.0 through 1.75.0 contain a path traversal vulnerability in the `rclone serve docker`
 volume plugin. newVolume() in cmd/serve/docker/volume.go computes a volume's mountpoint as
 filepath.Join(drv.root, name) from the attacker-supplied `name` field of a Docker VolumeDriver.Create
 request without verifying that the result stays within drv.root (default /var/lib/docker-volumes/rclone),
 and checkMountpoint() then creates that directory with file.MkdirAll before mounting. A volume name
 containing enough `..` components (e.g. "../../../../../../etc") therefore resolves outside the base
 directory, allowing anyone able to submit a VolumeDriver.Create request to the plugin socket — normally
 the Docker daemon, or a workload that can request named volumes in a multi-tenant orchestration setup — to
 make the privileged rclone plugin process create a directory and mount a remote filesystem specified in
 the same request at an arbitrary host path, shadowing or disrupting system directories. The advisory notes
 Volume.restoreState() had the same missing validation when reloading persisted volume state. Fixed in
 1.75.1. (CVE-2026-93987)

Solution

Update the rclone library and its related packages to version 1.75.1 or later.
