Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The flagged command execution is limited to opening the browser during interactive authentication, and agent enrollment sends the generated public key while retaining the private key locally. The package has no install hook that runs for registry installs, and no unrelated credential exfiltration or unauthorized account action was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-11-02T05:14:11.014Z - **Finished:** 2026-11-02T05:14:52.763Z - **Download time:** 507 ms - **Static scan time:** 359 ms - **AI review time:** 40882 ms - **Total time:** 41749 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:** No attack identified; the reviewed network and process behavior supports the SDK's authentication flows. - **Trigger:** An application calls SDK APIs; browser authentication is attempted only when credentials are unavailable and interactive conditions permit it. - **Impact:** No unauthorized collection, unrelated credential transfer, or unrequested account action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T05:14:52.763Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK sends authentication requests to the configured STACK API, stores credentials and agent keys under the user's .stack directory, and may launch the system browser for sign-in or enrollment. - **Rationale:** The flagged command execution is limited to opening the browser during interactive authentication, and agent enrollment sends the generated public key while retaining the private key locally. The package has no install hook that runs for registry installs, and no unrelated credential exfiltration or unauthorized account action was found. - **Files touched:** ~/.stack/credentials.json, ~/.stack/agents/\.json - **Network endpoints:** https://api.getstack.run, https://getstack.run, 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports dist/index.js as its entry point., The only lifecycle script is prepublishOnly, which cleans and builds the package., Agent enrollment sends a bearer token to the STACK API; the Ed25519 keypair is generated locally., Interactive browser authentication is gated on a TTY and can be disabled with STACK\_AUTH\_INTERACTIVE=false or CI. - **Evidence against:** The SDK reads local STACK credentials and sends them in authentication flows., Authentication may open a browser using child\_process. ## Affected versions and remediation This report applies to @getstackrun/sdk@1.3.0. - Review the evidence and your use of @getstackrun/sdk@1.3.0 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.
