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 runtime paths forward a saved service token to the selected mesh URL, and the URL can be overridden without an allowlist. Because the transfer requires running the service with that configuration and the default endpoint is package-aligned, this supports a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-22T20:57:00.932Z - **Finished:** 2026-10-22T21:00:16.735Z - **Download time:** 770 ms - **Static scan time:** 691 ms - **AI review time:** 194341 ms - **Total time:** 195803 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 saved Cloop device token can be sent to a configurable mesh endpoint. The source does not bind that token to its intended service when the endpoint is overridden. - **Trigger:** Run the workstation runner or MCP server with a token available and CLOOP\_MESH\_URL configured. - **Impact:** The configured endpoint receives the device token and may be able to use it to authenticate as the runner. - **Evidence paths:** dist/chunk-D5UZW42X.js, dist/box-XFXJEHHZ.js, dist/mcp-server-6RK4RQVI.js, dist/chunk-IJH4O27H.js, .lpm-dependency-evidence-64e1c4d8-3342-4c8e-8903-182c453e4477/1/npm-linux/lib/websocket.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T21:00:16.735Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The service passes the saved token to MeshSocket, which supplies it as a WebSocket subprotocol to the selected URL; the client places subprotocols in the request header. - **Rationale:** The runtime paths forward a saved service token to the selected mesh URL, and the URL can be overridden without an allowlist. Because the transfer requires running the service with that configuration and the default endpoint is package-aligned, this supports a warning rather than a publish block. - **Files touched:** ~/.cloop/credentials.json, dist/chunk-D5UZW42X.js, dist/box-XFXJEHHZ.js, dist/mcp-server-6RK4RQVI.js, dist/chunk-IJH4O27H.js, .lpm-dependency-evidence-64e1c4d8-3342-4c8e-8903-182c453e4477/1/npm-linux/lib/websocket.js - **Network endpoints:** https://mcp.mycloop.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The token loader returns a saved credential token or CLOOP\_TOKEN, while the mesh URL can be overridden with CLOOP\_MESH\_URL without destination validation., Both the workstation runner and MCP server pass the token and selected mesh URL to MeshSocket when starting a connection., MeshSocket supplies the token as a WebSocket subprotocol, and the ws implementation places supplied subprotocols in the request header., The runner reads metadata from other Claude project sessions and can include it in mesh presence; this is a separate presence feature from the credential transfer. - **Evidence against:** The manifest describes a Cloop runner and declares no install lifecycle hooks; the default mesh destination is Cloop's service., The credential exposure requires running the service with a configured mesh URL override; this is a warning about endpoint binding, not evidence of covert default exfiltration. ## Affected versions and remediation This report applies to @cloop/runner@0.3.15. - Review the evidence and your use of @cloop/runner@0.3.15 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.
