Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The scanner's env/network correlation matches opt-in licensed cloud sync, telemetry, and an explicit capture feature. Source inspection found no lifecycle hook, stealth execution, or concrete credential/data exfiltration chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-13T02:41:10.813Z - **Finished:** 2026-08-13T02:43:19.826Z - **Download time:** 508 ms - **Static scan time:** 1793 ms - **AI review time:** 126710 ms - **Total time:** 129013 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 confirmed malicious attack surface. The optional snapshot command may provision its declared browser dependency when explicitly invoked. - **Trigger:** User explicitly runs the snapshot capture helper. - **Impact:** Installs playwright-core in the package directory; no install-time execution or credential exfiltration was confirmed. - **Evidence paths:** package.json, scripts/capture-snapshot.mjs, server.js, lib/posthog.js, lib/capture-network-guard.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T02:43:19.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Conditional Playwright dependency installation for browser capture. - **Rationale:** The scanner's env/network correlation matches opt-in licensed cloud sync, telemetry, and an explicit capture feature. Source inspection found no lifecycle hook, stealth execution, or concrete credential/data exfiltration chain. - **Files touched:** scripts/capture-snapshot.mjs, package.json, server.js, lib/posthog.js, lib/capture-network-guard.js ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** Explicit snapshot helper can run npm install for Playwright if unavailable. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Network sync requires a configured license key., Telemetry hashes the license key and supports opt-out., Capture navigation rejects localhost and private/reserved targets. ## Affected versions and remediation This report applies to pincushion-mcp@1.11.7. - Review the evidence and your use of pincushion-mcp@1.11.7 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.
