## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Telemetry warning (can be blocked)
- **Public report status:** Published
- **Threat category:** Telemetry
- **Selected version:** 0.21.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

This version is suspicious because it automatically sends command telemetry and, when unauthenticated, includes the OS username and hostname without clearly disclosing that audit collection. The data goes to Shakers’ own API, and I found no evidence of the flagged unrelated credential redirection or install-time attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Default command auditing sends runtime telemetry that includes identifying machine details when unauthenticated.

- **Trigger:** Each CLI invocation, unless SHAKERS\_CLI\_NO\_AUDIT=1 is set.

- **Impact:** The vendor receives command activity and, for unauthenticated runs, identifying details about the local user and machine without a disclosed command-audit notice.

- **Evidence paths:** bin/shakers.js, bin/command-audit-worker.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-02T15:23:30.585Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** A detached worker POSTs the command name, scrubbed arguments, CLI version, and timestamp to the configured certification API. Without a valid session, it also includes the OS username and hostname; with a session, it includes the Shakers bearer token.

- **Rationale:** This version is suspicious because it automatically sends command telemetry and, when unauthenticated, includes the OS username and hostname without clearly disclosing that audit collection. The data goes to Shakers’ own API, and I found no evidence of the flagged unrelated credential redirection or install-time attack.

- **Network endpoints:** https://api.certifications.shakersworks.com/api/v1/cli/command-log

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The CLI starts command auditing on each invocation by default; it can be disabled with SHAKERS\_CLI\_NO\_AUDIT=1., The audit includes the command and scrubbed arguments. Without a valid session it also includes the OS username and hostname; with a session it sends a Shakers bearer token., The audit is POSTed to the configured certification API’s /cli/command-log route, which defaults to api.certifications.shakersworks.com.

- **Evidence against:** The manifest has no install, preinstall, or postinstall scripts., The inspected audit destination is Shakers’ own service; no fixed unrelated credential collector was found., The download-and-run update path is part of the explicit update command.
