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 connected runner sends metadata from other recent Claude sessions to the package’s service by default, with an opt-out. Because the user must connect the runner and the inspected data is limited to metadata, this supports a warning about conditional privacy exposure rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-22T20:56:42.940Z - **Finished:** 2026-10-22T20:59:08.433Z - **Download time:** 513 ms - **Static scan time:** 687 ms - **AI review time:** 144292 ms - **Total time:** 145493 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:** After connection, the runner can disclose metadata from recent Claude sessions outside the active thread in recurring presence updates. Sharing is enabled by default, creating a conditional privacy risk. - **Trigger:** The user connects and runs the Cloop runner in Claude mode. - **Impact:** The Cloop service receives metadata about other recent sessions unless sharing is disabled. - **Evidence paths:** dist/box-4G3Z6BGK.js, dist/chunk-GNNGDCKP.js, dist/chunk-LYB5H7VQ.js, dist/chunk-D5UZW42X.js, dist/chunk-IJH4O27H.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T20:59:08.433Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runner reads recent Claude session files for working directories and titles, then includes the results in presence messages sent over its mesh socket. - **Rationale:** The connected runner sends metadata from other recent Claude sessions to the package’s service by default, with an opt-out. Because the user must connect the runner and the inspected data is limited to metadata, this supports a warning about conditional privacy exposure rather than a publish block. - **Files touched:** dist/box-4G3Z6BGK.js, dist/chunk-GNNGDCKP.js, dist/chunk-LYB5H7VQ.js, dist/chunk-D5UZW42X.js, dist/chunk-IJH4O27H.js - **Network endpoints:** https://mcp.mycloop.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a CLI and has no install lifecycle hook., The runner scans recent Claude session files outside the active thread and extracts their working directories and titles., On connect, sharing is enabled unless the user selects the hide option; the runner includes the collected metadata in its presence payload., The presence socket sends that payload to the configured mesh endpoint, which defaults to the Cloop service., The websocket dependency code at the flagged location sets an ordinary Origin header. - **Evidence against:** The metadata is sent only after the user connects the runner, and the destination is the package’s Cloop service., The inspected code extracts session metadata, not transcript contents, and provides a hide-other-threads option. ## Affected versions and remediation This report applies to @cloop/runner@0.3.11. - Review the evidence and your use of @cloop/runner@0.3.11 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.
