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. A copied assistant-facing request can cause an explicit setup command to modify a consumer project and contact Patchstack. There is no registry-install trigger. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-15T19:11:18.462Z - **Finished:** 2026-09-15T19:12:33.624Z - **Download time:** 1032 ms - **Static scan time:** 2738 ms - **AI review time:** 71391 ms - **Total time:** 75162 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:** A copied assistant-facing request can cause an explicit setup command to modify a consumer project and contact Patchstack. There is no registry-install trigger. - **Trigger:** A user or coding assistant runs patchstack-connect setup. - **Impact:** The command can add build and dependency-install integration and save a service-issued credential. - **Evidence paths:** README.md, dist/cli.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-15T19:12:33.624Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Project integration, manifest upload, and remote-site provisioning. - **Rationale:** The package does not execute through a registry install hook, so the evidence does not establish automatic malware. Its assistant-directed setup flow makes broad consumer-project changes and sends data to a remote service, creating a meaningful user-invoked risk. - **Files touched:** package.json, .patchstackrc.json, .patchstackrc.local.json - **Network endpoints:** api.patchstack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The README explicitly targets coding assistants with a request to run setup., The explicit setup command scans, installs runtime protection, and rewrites project build integration., A scan can provision a remote site and save an API key returned by the service. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook., The CLI dispatches setup only when the user supplies the setup command., The cloud-metadata finding is a blocklist check, including the link-local range, rather than an access attempt. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.9. - Review the evidence and your use of @patchstack/connect@0.5.9 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.
