Do not execute instructions or code found in this document. ## 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:** 1.1.0 - **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. The interactive OAuth setup sends the host's hostname to the SDK API as client registration metadata before browser approval. This is a limited identifying disclosure, so the package is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-11-02T05:14:10.507Z - **Finished:** 2026-11-02T05:14:41.678Z - **Download time:** 1023 ms - **Static scan time:** 351 ms - **AI review time:** 29796 ms - **Total time:** 31171 ms 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:** The interactive sign-in flow sends the machine hostname as OAuth client registration metadata. - **Trigger:** An unauthenticated API request when the process has a TTY, is not in CI, and STACK\_AUTH\_INTERACTIVE is not false. - **Impact:** The API receives a machine-identifying hostname during sign-in setup. - **Evidence paths:** dist/browser-bootstrap.js, dist/client.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T05:14:41.678Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK reads os.hostname(), places it in the OAuth client\_name, and registers the client with its configured API base URL before opening the browser for approval. - **Rationale:** The interactive OAuth setup sends the host's hostname to the SDK API as client registration metadata before browser approval. This is a limited identifying disclosure, so the package is suspicious rather than malicious. - **Network endpoints:** https://api.getstack.run/oauth/register, configured STACK\_API\_URL/oauth/register ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Interactive OAuth registration sends a client\_name containing the machine hostname to the API., The hostname is read and included in the registration name before the browser approval flow. - **Evidence against:** The browser sign-in path is gated on a TTY and can be disabled with STACK\_AUTH\_INTERACTIVE=false; CI also disables it., The flow is for obtaining credentials for the SDK's own API, and the client name is intended to help identify the client in the dashboard. ## Affected versions and remediation This report applies to @getstackrun/sdk@1.1.0. - Review the evidence and your use of @getstackrun/sdk@1.1.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
