@marecgents/dsh-hub@0.0.2-rc.9

DeepSeek Harness desktop hub — Tauri 2.x shell + dsh web plugin layer. This npm package ships the plugin half (client UI + HTTP routes + cordis.patch.yml); the desktop shell ships as the NSIS installer (see build/).

AI Security Review

scanned 18d ago · by lpm-firewall-ai

Source supports explicit-command agent profile mutation, which the supplied policy classifies as warning-only. No inspected behavior supports a malicious publish block.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Running bin/dsh-web-sidecar.mjs or scripts/assemble-profile.mjs.

Impact

Changes which extensions the agent web profile can load, with hub activation guarded by an environment flag.

Mechanism

The assembly script updates profile bundle registration and links package-owned plugins into the profile.

AI rationale

Source supports explicit-command agent profile mutation, which the supplied policy classifies as warning-only. No inspected behavior supports a malicious publish block.

Evidence

bin/dsh-web-sidecar.mjsscripts/assemble-profile.mjscordis.patch.yml

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The sidecar explicitly runs the profile assembly script with the hub package root.
Assembly changes the web profile manifest to register the hub bundle and creates plugin junctions.
The bundle is disabled unless DSH_HUB_LAUNCHED is set to 1.
The npm postinstall hook can install the dsh CLI globally through selected npm registries.

Evidence against

Profile assembly is separate from the npm install hook and targets the hub's plugin registration.
Inspected source does not establish credential exfiltration, concealed payload execution, or broad agent control hijacking.
Legacy cleanup targets hub command shims and an old launcher shortcut.
