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. Static review shows a user-invoked browser client with no preinstall, install, or postinstall hook and no hidden payload. Local Chrome launch and authenticated relay calls match the package purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-26T03:52:40.531Z - **Finished:** 2026-09-26T03:53:20.933Z - **Download time:** 767 ms - **Static scan time:** 433 ms - **AI review time:** 39201 ms - **Total time:** 40402 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 unconsented attack surface was identified. The package is a user-started Chrome connector with no install hook. - **Trigger:** A person runs the r5d-browser CLI; nothing runs from npm install lifecycle hooks. - **Impact:** Browser control stays within the explicit client session. No hidden install-time mutation or exfiltration was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T03:53:20.933Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI launches a local Chrome process and talks to the configured HTTPS r5d origin with the supplied credential. - **Rationale:** Static review shows a user-invoked browser client with no preinstall, install, or postinstall hook and no hidden payload. Local Chrome launch and authenticated relay calls match the package purpose. ### 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 exposes only the r5d-browser CLI bin and has no install lifecycle scripts or self-dependency., Chrome is spawned locally from a resolved executable with a dedicated profile after the user starts the CLI., Page script execution is a named run\_js command inside the running browser runtime, not an install or import payload. - **Evidence against:** The CLI can send the caller-supplied r5d bearer token to a caller-configured HTTPS origin and can run relayed page scripts, which matches the stated remote-browser product. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790382603884.g0b6bb035b0b26b79c52fdb079dbc35d6df438233. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790382603884.g0b6bb035b0b26b79c52fdb079dbc35d6df438233 before allowing it.
