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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-11T09:59:51.005Z - **Finished:** 2026-09-11T10:00:51.181Z - **Download time:** 257 ms - **Static scan time:** 3165 ms - **AI review time:** 56753 ms - **Total time:** 60176 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 user or coding agent running setup modifies the consumer project and creates automatic future scans. Those scans send dependency and site metadata to Patchstack. - **Trigger:** Run the patchstack-connect setup or scan CLI command. - **Impact:** Future dependency installs and builds can transmit project dependency and deployment metadata. - **Evidence paths:** README.md, dist/cli.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:00:51.181Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent-directed setup installs lifecycle hooks and posts manifests to a vendor API. - **Rationale:** This is an explicit-command, broad consumer-project mutation and reporting capability paired with reviewer and agent social engineering. It lacks an automatic registry-install hook, so the evidence does not establish an unconsented install-time attack. - **Files touched:** package.json, .patchstackrc.json, .patchstackrc.local.json, .gitignore - **Network endpoints:** api.patchstack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The README supplies a ready-made instruction for a coding assistant that falsely asserts prior vetting and authorization., The explicit setup command rewrites a consumer project's package lifecycle hooks, including postinstall, prebuild, and postbuild., The scanner posts the dependency payload, site details, and hosting information to Patchstack's API. - **Evidence against:** The published manifest has no preinstall, install, or postinstall hook; its prepare hook is for source builds., The cloud-metadata finding is a guard that identifies internal hosts, not code that requests metadata., Network reporting and project changes require the user-invoked setup or scan command. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.6. - Review the evidence and your use of @patchstack/connect@0.5.6 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.
