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 and independently sourced credential create a concrete conditional exposure risk. Static inspection found no lifecycle trigger or separate evidence of malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-29T16:50:06.045Z - **Finished:** 2026-09-29T16:51:37.487Z - **Download time:** 1014 ms - **Static scan time:** 474 ms - **AI review time:** 89954 ms - **Total time:** 91442 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 can forward an existing R5D credential to a configured HTTPS origin. No automatic attack was identified. - **Trigger:** The user runs the browser start command with an origin supplied through options, environment, or configuration. - **Impact:** A misconfigured or attacker-controlled HTTPS origin could receive an existing service credential. - **Evidence paths:** dist/mjs/personal-main.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T16:51:37.487Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client selects that origin independently from the token source and posts requests with the token in a bearer authorization header. - **Rationale:** The configurable destination and independently sourced credential create a concrete conditional exposure risk. Static inspection found no lifecycle trigger or separate evidence of malicious intent. - **Files touched:** dist/mjs/personal-main.mjs - **Network endpoints:** https://r5d.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Package metadata exposes a browser CLI and contains no install lifecycle hook., The client accepts its service origin from command options, environment, or configuration and obtains a token from those sources., It sends that token as a bearer credential to the selected origin., The browser runtime can execute supplied JavaScript in the active page., Chrome remote debugging is bound to loopback. - **Evidence against:** The token forwarding occurs only after the user invokes the start command., No hidden install-time execution, destructive action, or package-owned unrelated endpoint was found. ## Affected versions and remediation This report applies to @ricsam/r5d-browser@0.0.191-prod.1790700019803.gd6db591440ba9d63a9accdeb5954aa88e3b2f601. - Review the evidence and your use of @ricsam/r5d-browser@0.0.191-prod.1790700019803.gd6db591440ba9d63a9accdeb5954aa88e3b2f601 before allowing it.
