Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package is a user-started macOS Chrome client for an r5d account, with no install hooks and no hidden credential or payload path. Remote page script and loopback forwards are explicit relay features of that CLI, not an unconsented attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-22T21:02:38.022Z - **Finished:** 2026-09-22T21:03:30.469Z - **Download time:** 506 ms - **Static scan time:** 425 ms - **AI review time:** 51515 ms - **Total time:** 52447 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:** No install-time or hidden attack surface was identified. Browser launch, credential use, and page script execution occur only after the user runs the r5d-browser CLI against their r5d account. - **Trigger:** User invocation of r5d-browser start or an absolute private keeper config, not package install or import of a library API. - **Impact:** Effects stay within the stated personal-browser product: a dedicated Chrome profile and account relay. No unconsented harvest, exfiltration, or install mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-22T21:03:30.469Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client launches local Chrome, authenticates to the configured HTTPS r5d origin, and applies relay actions including optional page JavaScript in that browser. - **Rationale:** The package is a user-started macOS Chrome client for an r5d account, with no install hooks and no hidden credential or payload path. Remote page script and loopback forwards are explicit relay features of that CLI, not an unconsented attack. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle scripts. The only entry is the user-run bin r5d-browser pointing at dist/mjs/main.mjs, which acts only after CLI arguments., Chrome is spawned from a resolved local executable with a dedicated profile. The launcher refuses the daily-driver Chrome directory and talks only to a loopback DevTools port it opened., Page JavaScript runs only inside an already launched browser when the authenticated personal relay sends a run\_js action after the user starts the client. - **Evidence against:** The bearer token is sent only to the HTTPS origin from the CLI, environment, or private r5dctl config, defaulting to https://r5d.dev, as authentication for that r5d API., Port forwards bind 127.0.0.1 and ::1 and only after the user starts the client and the same account relay returns forward definitions. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790110688453.g0fa50f294b0a5116a01d86a56e4d1d2d0f9b33eb. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790110688453.g0fa50f294b0a5116a01d86a56e4d1d2d0f9b33eb before allowing it.
