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 package has a real conditional credential-forwarding risk because HTTPS alone does not bind the selected origin to the token's intended service. Static inspection did not establish covert activation or malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-27T08:48:02.323Z - **Finished:** 2026-09-27T08:49:06.635Z - **Download time:** 760 ms - **Static scan time:** 455 ms - **AI review time:** 63096 ms - **Total time:** 64312 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 browser client forwards an r5d bearer token to its selected service origin. No covert attack was confirmed, but the origin is not limited to the default service. - **Trigger:** A user runs the browser command with a configured connection and token. - **Impact:** A token may be disclosed to an operator-selected HTTPS endpoint if an untrusted configuration or environment override is used. - **Evidence paths:** dist/mjs/personal-main.mjs, dist/mjs/browser-runtime.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T08:49:06.635Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Configuration or environment variables select an HTTPS origin; the client posts requests with the resolved bearer token. The service can also supply browser JavaScript actions. - **Rationale:** The package has a real conditional credential-forwarding risk because HTTPS alone does not bind the selected origin to the token's intended service. Static inspection did not establish covert activation or malicious intent. - **Files touched:** dist/mjs/personal-main.mjs, dist/mjs/browser-runtime.mjs - **Network endpoints:** https://r5d.dev/api/personal/resources ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a browser-control command-line entrypoint., The connection origin can come from command options, environment variables, or configuration, with HTTPS as the only destination restriction., The code selects an existing r5d token from environment or configuration and sends it as a bearer credential to that selected origin., Remote browser actions can construct and run supplied JavaScript inside a browser page. - **Evidence against:** The default connection origin is the r5d service and activation requires running the command with a credential., No install or lifecycle hook was declared in the inspected manifest. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.189-prod.1790498542138.g91e46aeabed5b5b13c7be7b912aae4e05df1e3d3. - Review the evidence and your use of @ricsam/r5d-browser@0.0.189-prod.1790498542138.g91e46aeabed5b5b13c7be7b912aae4e05df1e3d3 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.
