Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected entrypoints and package manifest do not establish malicious behavior, and the command execution found is tied to a configured test workflow. Selected dependency source was unavailable, so the package cannot be cleared as clean from this inspection alone. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 79.0% - **Started:** 2026-10-26T04:38:21.739Z - **Finished:** 2026-10-26T04:39:09.759Z - **Download time:** 1013 ms - **Static scan time:** 1651 ms - **AI review time:** 45355 ms - **Total time:** 48020 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:** No concrete attack was established in the inspected package code. A configured web-server command can run when its test workflow is invoked, but the inspected code does not show its captured output being exfiltrated. - **Trigger:** A caller invokes the browser test workflow with a web-server command configured. - **Impact:** The command runs with the local user's privileges; no unauthorized data transfer was established. Some selected dependency source remained unavailable for review. - **Review source:** ai\_review - **Reviewed:** 2026-10-26T04:39:09.759Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime starts the configured command and buffers up to a limited amount of its standard output and error. - **Rationale:** The inspected entrypoints and package manifest do not establish malicious behavior, and the command execution found is tied to a configured test workflow. Selected dependency source was unavailable, so the package cannot be cleared as clean from this inspection alone. - **Files touched:** package.json, dist/index.cjs, dist/index.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 79.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package exports CommonJS and ESM runtime entrypoints and declares dependencies used by them., The bound-browser runtime requires an explicit profile and checks requested browser operations against that profile., The server can start a configured web-server command and capture its output; these excerpts do not show output being sent to a publisher-selected recipient., A selected dependency source path was unavailable during inspection, leaving part of the runtime behavior unresolved. - **Evidence against:** The manifest has no install lifecycle script, and the inspected runtime excerpts do not establish an automatic command-output transfer or other concrete attack. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.53. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.53 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.
