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. An explicit setup command makes persistent consumer-project changes and enables later dependency reporting during install and build hooks. The runtime guard can also report blocked-request metadata. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-11T09:01:46.092Z - **Finished:** 2026-09-11T09:03:15.051Z - **Download time:** 260 ms - **Static scan time:** 3293 ms - **AI review time:** 85404 ms - **Total time:** 88959 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:** An explicit setup command makes persistent consumer-project changes and enables later dependency reporting during install and build hooks. The runtime guard can also report blocked-request metadata. - **Trigger:** A user runs patchstack-connect setup; later project installs or builds run the added hooks. - **Impact:** Dependency inventory and site metadata are sent to Patchstack; the injected widget loads remote browser code; blocked request metadata may be reported. - **Evidence paths:** dist/cli.js, dist/index.cjs, dist/protect.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T09:03:15.051Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Project script mutation, manifest reporting, widget injection, and optional firewall telemetry. - **Rationale:** The package creates persistent install-hook and reporting behavior only after an explicit user command. This is a real dangerous capability but the source does not establish malicious intent or an unconsented registry-install attack. - **Files touched:** package.json, .patchstackrc.json, .patchstackrc.local.json, .gitignore, index.html, public/index.html, src/app.html - **Network endpoints:** https://api.patchstack.com/monitor/pulse/manifest, https://api.patchstack.com/api/logs/log, https://cdn.patchstack.com/patchstack-widget.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The explicit setup command rewrites the consumer project's package scripts to run its scan at postinstall and around builds., The scan posts a dependency manifest and site metadata to the Patchstack API., Setup can inject a remotely hosted Patchstack widget into application HTML., The runtime guard can send blocked-request metadata, including path, IP address, and user agent, when reporting is enabled. - **Evidence against:** The published manifest has no preinstall, install, or postinstall hook; its prepare hook is a build command., The project-script mutation is reached through the explicit setup CLI command, not package installation or import., Network requests use stated Patchstack endpoints and no source evidence shows arbitrary payload execution, secret harvesting, or destructive behavior., The guard's reporting requires a credential and provides configuration and environment opt-outs. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.5. - Review the evidence and your use of @patchstack/connect@0.5.5 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.
