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 configurable destination is not host-bound before credential forwarding, creating a concrete conditional exposure risk. The inspected code otherwise shows user-invoked browser automation and no lifecycle-based or hidden exfiltration behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-29T01:15:24.671Z - **Finished:** 2026-09-29T01:16:37.866Z - **Download time:** 765 ms - **Static scan time:** 486 ms - **AI review time:** 71943 ms - **Total time:** 73195 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 user-invoked browser relay accepts a configurable HTTPS origin and forwards an existing r5d credential to it. No confirmed covert attack or install-time attack was identified. - **Trigger:** Running the CLI start command with a configured origin and token. - **Impact:** A token intended for one service could be exposed if an operator configures an untrusted HTTPS origin. - **Evidence paths:** dist/mjs/personal-main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T01:16:37.866Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The relay derives an origin from options, environment, or config and sends the token in an Authorization header to that origin. - **Rationale:** The configurable destination is not host-bound before credential forwarding, creating a concrete conditional exposure risk. The inspected code otherwise shows user-invoked browser automation and no lifecycle-based or hidden exfiltration behavior. - **Files touched:** dist/mjs/personal-main.mjs - **Network endpoints:** https://r5d.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Package metadata selects a JavaScript module entrypoint., The CLI activates its browser client only through the start command., The connection origin can come from an option, environment variable, or config file; it is restricted to HTTPS but not to a host allowlist., The client sends the selected token as a Bearer credential to the selected origin., The launcher starts the configured Chrome executable using a loopback debugging port., The browser runtime executes supplied run\_js code in the current browser page. - **Evidence against:** No npm lifecycle hook is declared in the inspected package metadata., No hidden recipient, unrelated network host, or install-time execution was found in the inspected entrypoints. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.190-prod.1790636572228.gbad0936ff3327d40d4da94c6be11353f3bc8aad0. - Review the evidence and your use of @ricsam/r5d-browser@0.0.190-prod.1790636572228.gbad0936ff3327d40d4da94c6be11353f3bc8aad0 before allowing it.
