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. 18 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:** 0.3.2 - **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. The install-time network behavior is disclosed package telemetry, and its disable flags are checked before the telemetry routine proceeds. The runtime hint is ordinary query error handling; the scanner’s similarity label is not supported by inspected malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-16T01:43:59.570Z - **Finished:** 2026-10-16T01:45:08.632Z - **Download time:** 1020 ms - **Static scan time:** 972 ms - **AI review time:** 67070 ms - **Total time:** 69062 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 surface was identified. The install hook performs disclosed package telemetry. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** Pseudonymous installation analytics are sent by default; the inspected source does not collect credentials or application data. - **Review source:** ai\_review - **Reviewed:** 2026-10-16T01:45:08.632Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook sends a random installation ID, a salted project identity, and package and system metadata to a configured PostHog capture endpoint; it honors telemetry disable flags. - **Rationale:** The install-time network behavior is disclosed package telemetry, and its disable flags are checked before the telemetry routine proceeds. The runtime hint is ordinary query error handling; the scanner’s similarity label is not supported by inspected malicious behavior. - **Network endpoints:** https://dgoeivjus9jfp.cloudfront.net ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest routes installation through the package postinstall entry., The install event sends a random installation ID, a salted project identity, and package and system metadata., The install notice describes the telemetry, and the routine honors the stated disable flags., The telemetry endpoint is configured as a PostHog capture endpoint, with an environment override., The runtime hint is ordinary MCP query error handling in both module formats., The declaration entry describes parser types, not executable behavior. - **Evidence against:** Installation telemetry runs by default; the opt-out flags do not require affirmative consent, and the project identity is hashed rather than omitted. ## Affected versions and remediation This report applies to @openuidev/lang-core@0.3.2. - Review the evidence and your use of @openuidev/lang-core@0.3.2 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.
