Linux Distros Unpatched Vulnerability : CVE-2026-93987

medium Nessus Plugin ID 348340

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.
