specrails-desktop@2.19.1

AI Security Review

scanned 4d ago · by lpm-firewall-ai

No confirmed malicious attack surface found. Risky primitives are aligned with a desktop AI/project manager: local server control, user-invoked AI CLI spawning, optional prerequisite install, mobile companion signaling, and local app state files.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

User runs specrails-desktop commands or enables app features.

Impact

No evidence of credential harvesting, hidden exfiltration, install-time execution, persistence, or destructive behavior.

Mechanism

user-invoked local orchestration and feature-specific subprocess/network operations

Rationale

Static inspection found powerful but expected desktop automation capabilities gated by explicit user/app actions, with no lifecycle hook or hidden exfiltration path. Scanner findings map to package-aligned code rather than concrete malicious behavior.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with medium false-positive risk.

Evidence for block

Evidence against

package.json has no install/preinstall/postinstall lifecycle hooks; only bin cli/dist/specrails-desktop.js.
cli/dist/specrails-desktop.js talks only to localhost manager by default and otherwise user-invokes claude with the supplied command.
server/dist/providers/gemini-adapter.js is a provider adapter spawning local gemini CLI; no import/install-time execution.
server/dist/plugins/prereq-installer.js installs uv from astral.sh only when installPrerequisite('uv') is called, with test noop gate.
server/dist/terminal-shell-integration.js writes temporary shell shims under ~/.specrails for terminal sessions, not persistent shell profiles.
client/dist/assets/html.worker-CQP8QQsS.js Unicode hits are bundled HTML entity data/worker content, not Trojan Source control flow.

2// App-wide owner of a SINGLE persistent Chromium context for "Add Spec from a

3// website". Its profile (cookies, logins, localStorage) lives in ONE GLOBAL dir

4// under $HOME, so the captured browser shares its session across every project —

5// log in once, and any project's capture window sees those cookies.

6//

7// Why a shared singleton (not per-project): a persistent Chromium profile takes

8// an EXCLUSIVE on-disk lock, so exactly one context may open a given userDataDir.

9// Pointing every project at one global dir therefore REQUIRES a single shared

10// context; each per-project BrowserCaptureManager opens its own pages in it

11// (pages are isolated enough for capture, cookies are shared). The context is

12// launched lazily on first use and closed once at app shutdown.
