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. Remote vendor rules can choose request fields or raw request content for capture. The guard includes that capture data in authenticated detection posts to the vendor service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-08T10:24:24.746Z - **Finished:** 2026-09-08T10:26:46.037Z - **Download time:** 762 ms - **Static scan time:** 3168 ms - **AI review time:** 137359 ms - **Total time:** 141291 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:** Remote vendor rules can choose request fields or raw request content for capture. The guard includes that capture data in authenticated detection posts to the vendor service. - **Trigger:** A consumer runs setup or installs the runtime guard, then a request matches a vendor-supplied rule. - **Impact:** Sensitive request values, routes, client IP addresses, and user agents can leave the application. - **Evidence paths:** dist/protect.cjs, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T10:26:46.037Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-rule-controlled request capture and detection reporting. - **Rationale:** The runtime combines remote control over request capture with authenticated transmission of captured data to a package-controlled endpoint. Explicit setup does not remove the risk because it persists automatic hooks in the consumer project. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** package.json - **Network endpoints:** api.patchstack.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** The runtime fetches rules from the vendor service, allowing the service to control capture behavior., A rule can select named request fields or raw request content, and captured values are retained in detection events., Detection events, including capture data, are posted to the vendor endpoint with authentication., The setup command rewrites a consumer project's install and build hooks to make scanning persistent. - **Evidence against:** The package manifest has no preinstall, install, or postinstall hook of its own., The capture size is bounded and response data is explicitly excluded, but request values can still contain secrets. ## Affected versions and remediation This report applies to @patchstack/connect@0.4.2. - Review the evidence and your use of @patchstack/connect@0.4.2 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.
