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:** 0.2.0-rc.29 - **Selected version is latest:** Yes - **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 gates telemetry on a host-side enablement response and sends it to the same-origin workbench host, but the logged fields can include document quotes and agent request text. That content exceeds ordinary operational telemetry and creates a user-content exposure risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-04T13:47:05.730Z - **Finished:** 2026-11-04T13:48:13.138Z - **Download time:** 509 ms - **Static scan time:** 1392 ms - **AI review time:** 65506 ms - **Total time:** 67408 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:** Host-enabled runtime telemetry may send document excerpts and agent request text to the workbench operator. - **Trigger:** Automatically when a Workbench is constructed; collection and sending proceed only if the host reports telemetry enabled. - **Impact:** The operator may receive document snippets and user request content through telemetry. - **Evidence paths:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Review source:** ai\_review - **Reviewed:** 2026-11-04T13:48:13.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The operation logger records UI and workbench events, including quote and request-text attributes, then sends batches to the same-origin telemetry endpoint. - **Rationale:** The package gates telemetry on a host-side enablement response and sends it to the same-origin workbench host, but the logged fields can include document quotes and agent request text. That content exceeds ordinary operational telemetry and creates a user-content exposure risk. - **Files touched:** src/workbench.ts, src/telemetry.ts, src/workspace-client.ts - **Network endpoints:** /api/presmium/telemetry ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Workbench construction starts the operation logger automatically., When the host enables collection, the logger records control clicks and sends queued operations., Operation records can include selected document quotes and agent request text., The logger sends batches to the same-origin \`/api/presmium/telemetry\` endpoint. - **Evidence against:** Collection is gated on the host reporting \`enabled: true\`., The endpoint is the workbench host; no unrelated collector was identified., The package metadata lists no lifecycle scripts. ## Affected versions and remediation This report applies to @lincyaw/workbench@0.2.0-rc.29. - Review the evidence and your use of @lincyaw/workbench@0.2.0-rc.29 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.
