Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 14 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.16 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection shows disclosed installation telemetry with opt-out controls and runtime telemetry gated by explicit opt-in. The package’s executable behavior supports its stated parser and telemetry functions, with no concrete malicious behavior found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-08T20:26:49.514Z - **Finished:** 2026-10-08T20:27:27.388Z - **Download time:** 774 ms - **Static scan time:** 906 ms - **AI review time:** 36193 ms - **Total time:** 37874 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 malicious attack was identified. Installation runs disclosed, opt-out telemetry, while runtime telemetry requires opt-in. - **Trigger:** Package installation triggers the postinstall telemetry; runtime events require application calls and an explicit telemetry enable flag. - **Impact:** The inspected behavior is limited to package-aligned telemetry; no credential theft, arbitrary code execution, or destructive action was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T20:27:27.388Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall sends a salted project identifier and environment metadata to the PostHog capture endpoint. Runtime telemetry sends sampled usage summaries when enabled. - **Rationale:** Source inspection shows disclosed installation telemetry with opt-out controls and runtime telemetry gated by explicit opt-in. The package’s executable behavior supports its stated parser and telemetry functions, with no concrete malicious behavior found. - **Files touched:** package.json, postinstall.cjs, dist/postinstall.cjs, dist/index.cjs, dist/shared-BuVpfVsg.cjs - **Network endpoints:** https://dgoeivjus9jfp.cloudfront.net ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook sends package-aligned installation telemetry with a salted project identifier and runtime and environment metadata., The install telemetry honors explicit disable flags and posts to the configured PostHog capture endpoint., Runtime telemetry requires an explicit enable flag, honors disable flags, and samples events at 10%., The declaration entrypoint contains parser and type definitions. ## Affected versions and remediation This report applies to @openuidev/lang-core@0.2.16. - Review the evidence and your use of @openuidev/lang-core@0.2.16 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.
