It also proxies relay-controlled HTTP and WebSocket traffic to the local DSH service using its minted authentication cookie. - **Trigger:** Loading the plugin with a token and automatic connection enabled. - **Impact:** A relay operator can obtain local secrets such as dotfiles and access the local DSH web interface through the agent. - **Evidence paths:** lib/index.js, lib/core.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T09:26:32.804Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Relay-controlled arbitrary-file read and authenticated local-service proxy. - **Attack narrative:** When loaded with a token, the package connects to a relay and registers that token. Relay messages select the artifact route, whose path parameter reaches fs.readFileSync without a directory allowlist; any dotfile is accepted. The file bytes are sent in relay responses. The same relay controls HTTP and WebSocket forwarding to the local DSH service, where the agent can add a minted authentication cookie. - **Rationale:** The source implements a remote-controlled channel for reading arbitrary local dotfiles and returning their contents over a relay, alongside authenticated proxying of a local service. This is a concrete data-exfiltration and remote-control surface, not merely ordinary telemetry. - **Files touched:** lib/index.js, lib/core.js - **Network endpoints:** wss://relay.example.com/agent ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The plugin automatically starts a relay agent when configured with a token., The agent sends its registration token and host system information to the relay., Relay-controlled requests can invoke an artifact endpoint., That endpoint accepts any dotfile path and reads the selected local file before returning it over the relay., The agent also forwards relay requests into the authenticated local DSH web service. - **Evidence against:** The manifest has no install, postinstall, or preinstall lifecycle hook., The only fixed relay URL is an example placeholder; a real relay URL is supplied by configuration. ## Public findings ### 1.
