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 configured environment endpoint can receive authentication derived from an existing Patchstack credential. No covert default recipient or install-time attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-28T20:32:53.630Z - **Finished:** 2026-09-28T20:34:21.197Z - **Download time:** 770 ms - **Static scan time:** 2946 ms - **AI review time:** 83849 ms - **Total time:** 87567 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 configured environment endpoint can receive authentication derived from an existing Patchstack credential. No covert default recipient or install-time attack was identified. - **Trigger:** Running the client or enabling the protection reporter with Patchstack endpoint and credential environment settings. - **Impact:** A mistaken or attacker-controlled runtime environment configuration could expose a Patchstack credential to an operator-selected HTTPS endpoint. - **Review source:** ai\_review - **Reviewed:** 2026-09-28T20:34:21.197Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code accepts an HTTPS endpoint or API base from environment configuration, reads Patchstack credentials, and sends bearer or client-credential authentication to that destination. - **Rationale:** The package can forward existing service credentials to unrestricted operator-configured HTTPS endpoints. Explicit configuration reduces evidence of covert intent but does not bind credentials to their intended service. - **Files touched:** dist/index.js, dist/protect.edge.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package accepts a runtime endpoint from an environment variable and treats it as trusted., The client obtains a bearer token and sends it to the configured endpoint., The edge guard reads an existing API key from the environment., The edge reporter exchanges that key at a configurable HTTPS API base., No registry install hook is declared; the only lifecycle-related script is prepare. - **Evidence against:** The custom destinations must be HTTPS or localhost, and configuration-file endpoints require explicit confirmation., The observed behavior is consistent with configurable Patchstack API clients, with no hidden default third-party recipient found. ## Affected versions and remediation This report applies to @patchstack/connect@0.5.15. - Review the evidence and your use of @patchstack/connect@0.5.15 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.
