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 flagged process execution launches installed Chrome, and dynamic evaluation implements browser operations rather than a hidden host payload. Inspected source shows no concrete malicious chain; authentication and configurable service requests are consistent with the client’s functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-05T04:52:05.450Z - **Finished:** 2026-10-05T04:53:19.270Z - **Download time:** 1007 ms - **Static scan time:** 521 ms - **AI review time:** 72291 ms - **Total time:** 73820 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 concrete attack was identified. Inspected execution and network behavior supports an authenticated browser automation client. - **Trigger:** The user invokes start or supplies a private browser keeper configuration. - **Impact:** Browser control and private state creation are expected functionality; no covert exfiltration or malicious installation behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-05T04:53:19.270Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client launches local Chrome, receives browser operations, and executes supplied JavaScript in browser pages. - **Rationale:** The flagged process execution launches installed Chrome, and dynamic evaluation implements browser operations rather than a hidden host payload. Inspected source shows no concrete malicious chain; authentication and configurable service requests are consistent with the client’s functionality. - **Network endpoints:** https://r5d.dev, 127.0.0.1 ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle hooks or runtime self-dependency., The Chrome launcher spawns a validated local executable with a dedicated profile and loopback debugging., Browser JavaScript execution handles caller-provided code inside page.evaluate, consistent with browser automation., The CLI activates the personal browser through the start command or an explicit private configuration., Authentication requests target the configured service origin, reject redirects, and use service credentials; no unrelated recipient was identified., The configured Chromium factory verifies a private approval file against its expected digest and restricts browser traffic to approved loopback origins. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.194-prod.1791174951663.g5660debf54d7649e6f1a445b2920f376ae9d8f34. - Review the evidence and your use of @ricsam/r5d-browser@0.0.194-prod.1791174951663.g5660debf54d7649e6f1a445b2920f376ae9d8f34 before allowing it.
