Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source establishes conditional forwarding of existing credentials to an unrestricted configured HTTPS origin, warranting a warning. The scanner's execution findings do not establish malware: Chrome is launched locally and supplied JavaScript executes in a browser page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-03T22:04:46.386Z - **Finished:** 2026-10-03T22:05:58.647Z - **Download time:** 1031 ms - **Static scan time:** 486 ms - **AI review time:** 70743 ms - **Total time:** 72261 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:** A configured HTTPS server can receive an existing r5d credential. This establishes conditional credential exposure, without a confirmed malicious recipient or covert attack. - **Trigger:** Run r5d-browser start with a changed server origin while an existing credential remains available. - **Impact:** An operator-selected server could obtain a credential intended for another r5d service. - **Evidence paths:** dist/mjs/personal-main.mjs, dist/mjs/cli-options.mjs, dist/mjs/main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-03T22:05:58.647Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Server selection and credential fallback are independent; the registration request forwards the token to the selected origin. - **Rationale:** Source establishes conditional forwarding of existing credentials to an unrestricted configured HTTPS origin, warranting a warning. The scanner's execution findings do not establish malware: Chrome is launched locally and supplied JavaScript executes in a browser page. - **Network endpoints:** https://r5d.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The browser client falls back to existing environment credentials and the default r5dctl configuration token., Server selection accepts any HTTPS origin, without binding saved credentials to their original service., The client sends the selected token as a Bearer authorization header to the selected server., The start command activates the personal browser client; changing the server does not require supplying a new credential., The manifest has no install hooks or runtime self-dependency; the launcher starts a local Chrome executable., Dynamic JavaScript execution is an input-driven browser-page action. - **Evidence against:** The default server is https://r5d.dev, and requests reject redirects., No hidden recipient, credential theft intent, or remote payload execution was established. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.194-prod.1791058089169.gbb02d5f45e95b54ee2cdb3751dc73f40b6cb0052. - Review the evidence and your use of @ricsam/r5d-browser@0.0.194-prod.1791058089169.gbb02d5f45e95b54ee2cdb3751dc73f40b6cb0052 before allowing it.
