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. The explicit CLI activation and package-aligned default reduce stealth concerns, but HTTPS alone does not restrict a reusable credential to its intended service. The unrestricted origin selection plus token forwarding warrants a non-blocking warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-28T06:31:17.443Z - **Finished:** 2026-09-28T06:32:35.476Z - **Download time:** 1023 ms - **Static scan time:** 473 ms - **AI review time:** 76536 ms - **Total time:** 78033 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 explicitly started browser relay can send an existing r5d credential to an HTTPS origin chosen through options, environment, or configuration. That origin can then provide actions executed in the connected browser. - **Trigger:** The user runs r5d-browser start with a selected or configured origin. - **Impact:** A configured non-r5d endpoint could receive the service credential and control the connected browser session. - **Evidence paths:** dist/mjs/personal-main.mjs, dist/mjs/browser-runtime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T06:32:35.476Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client forwards a bearer token to the selected relay and dispatches returned browser actions, including supplied page JavaScript. - **Rationale:** The explicit CLI activation and package-aligned default reduce stealth concerns, but HTTPS alone does not restrict a reusable credential to its intended service. The unrestricted origin selection plus token forwarding warrants a non-blocking warning. - **Files touched:** dist/mjs/personal-main.mjs, dist/mjs/browser-runtime.mjs - **Network endpoints:** https://r5d.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Package metadata defines a CLI entry point and contains no install lifecycle hook., The networked browser client starts only through the explicit start command., The client accepts its HTTPS origin from command options, environment variables, or configuration and obtains a reusable service token from those sources., Each relay request sends that token as a bearer credential to the selected origin., The relay continuously accepts remote actions, including a JavaScript escape hatch that evaluates supplied code in the browser page. - **Evidence against:** The default origin is the package-aligned r5d service., The origin parser requires HTTPS and rejects embedded URL credentials. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790576235476.ga922cc6c91ba099b9eb51a1018d554e54207deb3. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790576235476.ga922cc6c91ba099b9eb51a1018d554e54207deb3 before allowing it.
