# agent-device: authenticated remote callers can read daemon-host files

Link for people: https://infrastack.ai/live/CVE-2026-129130 (this .md is for agents)

agent-device, a tool that lets AI agents drive devices, versions 0.21.36 before 0.21.37 let an authenticated remote caller open file:// URLs through its /rpc endpoint. The caller can then read any plaintext file the daemon account can read.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed agent-device version, e.g. `npm ls agent-device` in the project, and compare it with `0.21.37`.
- Confirm whether the daemon's /rpc endpoint is reachable from outside the machine.

## Fix

- agent-device: move to `0.21.37` or later.

## From the sources

agent-device from 0.21.36 before 0.21.37 contains a local file disclosure vulnerability that allows authenticated remote callers to read daemon-host files by opening file:// URLs. Attackers can send an open command with a file:// target through /rpc, then issue snapshot to read any plaintext file readable by the daemon account.
