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. The scanner's execution findings correspond to local Chrome launch and browser-page automation, rather than a demonstrated download-and-execute attack. Reusing existing service credentials with an unrestricted configurable destination warrants a warning under the credential forwarding policy. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-04T23:41:40.109Z - **Finished:** 2026-10-04T23:43:00.871Z - **Download time:** 778 ms - **Static scan time:** 538 ms - **AI review time:** 79445 ms - **Total time:** 80762 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:** The personal browser client can forward an existing r5d credential to a configurable HTTPS origin. This establishes conditional credential exposure, but no confirmed malicious attack. - **Trigger:** Run r5d-browser start with an alternate base URL while an existing service credential is available. - **Impact:** An alternate server could receive a credential intended for the user's r5d service. - **Evidence paths:** dist/mjs/cli-options.mjs, dist/mjs/personal-main.mjs, dist/mjs/main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-04T23:43:00.871Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Origin selection and credential selection are independent; the selected token is sent in the authorization header without restricting the destination host. - **Rationale:** The scanner's execution findings correspond to local Chrome launch and browser-page automation, rather than a demonstrated download-and-execute attack. Reusing existing service credentials with an unrestricted configurable destination warrants a warning under the credential forwarding policy. - **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 default configuration is the existing r5dctl configuration; authentication can reuse its token or service environment credentials., The server origin is configurable and checked for HTTPS syntax, without a destination host allowlist., Requests send the selected token as bearer authentication to the selected origin., The start command reaches the personal browser client through its update runner., The Chrome launcher spawns a local executable using browser arguments and a loopback debugging port., Dynamic code execution implements the run\_js browser action inside a page. - **Evidence against:** No npm lifecycle hooks or runtime self-dependency appear in package.json., The inspected launcher does not download an executable; its Google Chrome URL is installation guidance., No covert recipient or concrete malware behavior was established. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.194-prod.1791156868699.gfda9770eb69972f6bfa39b87968a8f2a4aec024e. - Review the evidence and your use of @ricsam/r5d-browser@0.0.194-prod.1791156868699.gfda9770eb69972f6bfa39b87968a8f2a4aec024e before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
