Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.2.32 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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's on/off commands silently send action and harness telemetry to the configured router. The payload is limited and the request follows an explicit user command, but the source does not disclose this runtime reporting, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-31T20:51:10.602Z - **Finished:** 2026-10-31T20:52:03.274Z - **Download time:** 515 ms - **Static scan time:** 340 ms - **AI review time:** 51816 ms - **Total time:** 52672 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:** Undisclosed runtime telemetry reports routing state changes to the configured router. - **Trigger:** A user runs a routing on/off command through install.sh. - **Impact:** The router can record which client harness the user enabled or disabled. The source does not disclose this reporting to users. - **Evidence paths:** install.sh - **Review source:** ai\_review - **Reviewed:** 2026-10-31T20:52:03.274Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script sends an authenticated POST to the configured router's /v1/client-events endpoint with the action and harness fields. - **Rationale:** The package's on/off commands silently send action and harness telemetry to the configured router. The payload is limited and the request follows an explicit user command, but the source does not disclose this runtime reporting, so this warrants a warning rather than a block. - **Files touched:** install.sh - **Network endpoints:** Configured router base URL: /v1/client-events ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package has no install, preinstall, or postinstall hook; its only declared script is prepack., After routing on/off changes, install.sh sends a POST to /v1/client-events containing the action and harness., The event uses the endpoint from the installed configuration, which the source says is the user's own router., The event is triggered by an explicit routing on/off command. - **Evidence against:** The event payload contains only an action and harness, not host, user, path, credential, or project details., The request goes to the configured router and is associated with an explicit user state change., The package is described as an installer and router for supported coding agents. ## Affected versions and remediation This report applies to @weave-os/router@0.2.32. - Review the evidence and your use of @weave-os/router@0.2.32 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.
