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 Chrome client with no install lifecycle, and its token is sent only to the configured r5d HTTPS origin. Local Chrome spawn and in-page run\_js match that browser-control purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-27T14:59:14.611Z - **Finished:** 2026-09-27T15:00:41.132Z - **Download time:** 767 ms - **Static scan time:** 440 ms - **AI review time:** 85313 ms - **Total time:** 86521 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 was identified. Browser launch, page actions, and authenticated relay calls are user-invoked features of this Chrome client. - **Trigger:** A user runs the r5d-browser CLI; there is no registry install hook. - **Impact:** No unconsented credential theft, persistence, or foreign agent-control mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T15:00:41.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client launches a local Chrome profile and sends the r5d bearer token only to the selected HTTPS product origin. - **Rationale:** The package is a user-started Chrome client with no install lifecycle, and its token is sent only to the configured r5d HTTPS origin. Local Chrome spawn and in-page run\_js match that browser-control purpose. - **Network endpoints:** https://r5d.dev ### 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 the r5d-browser CLI bin and has no preinstall, install, or postinstall scripts., Chrome is started with spawn only after the executable path is validated, and only when the launcher runs., Page JavaScript runs only for an explicit browser run\_js action inside the controlled page., Account requests use a caller-selected HTTPS origin, defaulting to https://r5d.dev, with the r5d credential. - **Evidence against:** Remote browser control, loopback port forwards, and run\_js are powerful, but they start only after the user runs the CLI and they talk to the same product origin. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790463964002.gbcfce585c96c8eb0c668f572ed7d664c7e7d8a4e. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790463964002.gbcfce585c96c8eb0c668f572ed7d664c7e7d8a4e before allowing it.
