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 relay for an r5d account, with no install hooks or hidden payload. Credential use and remote page control match that CLI and stay bound to the configured HTTPS origin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-27T15:24:55.091Z - **Finished:** 2026-09-27T15:26:10.159Z - **Download time:** 772 ms - **Static scan time:** 481 ms - **AI review time:** 73815 ms - **Total time:** 75068 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 found. Browser launch, token use, page script execution, and loopback forwarding run only after the user starts r5d-browser and point at that user's configured r5d HTTPS origin. - **Trigger:** User invocation of the r5d-browser CLI, not package install or a foreign lifecycle hook. - **Impact:** Effects stay within the user-started browser session and the chosen r5d environment. No unsolicited credential theft, persistence, or consumer-project mutation was identified. - **Review source:** ai\_review - **Reviewed:** 2026-09-27T15:26:10.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI launches local Chrome and authenticates to the configured HTTPS origin with the r5d credential, then applies browser actions requested through that relay. - **Rationale:** The package is a user-started Chrome relay for an r5d account, with no install hooks or hidden payload. Credential use and remote page control match that CLI and stay bound to the configured HTTPS origin. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** package.json exposes only the r5d-browser bin and dist/mjs/main.mjs entry, with no preinstall, install, or postinstall script., launchStableChrome starts a local macOS Chrome process only when the CLI launches a session., run\_js evaluates caller-supplied page script inside BrowserRuntime as an explicit browser action, not at install time., The personal client posts its bearer token only to an HTTPS origin taken from the CLI, environment, or r5d config, defaulting to https://r5d.dev. - **Evidence against:** The HTTPS origin is not limited to a fixed host allowlist, so a configured base URL can receive the saved r5d token., After the user starts the client, the connected account can drive Chrome, including run\_js and loopback port forwards. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790516962319.gde56d4164488b5d1eb3e8dfcf98e9d2b0e676777. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790516962319.gde56d4164488b5d1eb3e8dfcf98e9d2b0e676777 before allowing it.
