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 package performs package-aligned installation telemetry, with a notice and working opt-out flags; runtime telemetry requires explicit opt-in. The inspected source shows no concrete attack behavior, so the scanner’s execution and network indicators do not warrant a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-08T20:26:49.522Z - **Finished:** 2026-10-08T20:27:34.220Z - **Download time:** 768 ms - **Static scan time:** 900 ms - **AI review time:** 43029 ms - **Total time:** 44698 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 attack was identified. The install hook sends disclosed, pseudonymous installation telemetry, while runtime telemetry is opt-in. - **Trigger:** npm installation triggers the postinstall hook; runtime telemetry is gated on explicit opt-in and sampled system-prompt generation. - **Impact:** Telemetry reveals a pseudonymous project identifier and installation metadata to the collector; inspected source does not show credential or prompt collection. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T20:27:34.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook hashes project identity with a salt and sends installation metadata to the configured PostHog capture endpoint; disable flags suppress it. - **Rationale:** The package performs package-aligned installation telemetry, with a notice and working opt-out flags; runtime telemetry requires explicit opt-in. The inspected source shows no concrete attack behavior, so the scanner’s execution and network indicators do not warrant a warning. - **Files touched:** package.json, postinstall.cjs, dist/postinstall.cjs, dist/shared-BuVpfVsg.cjs, dist/index.cjs, dist/index.d.cts - **Network endpoints:** https://dgoeivjus9jfp.cloudfront.net ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs a postinstall telemetry entry., Postinstall sends a salted project identifier and installation metadata to a PostHog capture endpoint; the source displays a telemetry notice., Telemetry honors OPENUI\_TELEMETRY\_DISABLED and DO\_NOT\_TRACK; runtime telemetry requires explicit opt-in., The runtime entry is OpenUI Lang parser and prompt-generation code, and its declaration file describes openui-lang expressions. - **Evidence against:** The inspected telemetry payload contains a salted project identifier and platform/package metadata, not raw repository URLs, paths, credentials, prompts, or source code., No concrete malicious behavior was identified in the inspected entrypoints. ## Affected versions and remediation This report applies to @openuidev/lang-core@0.3.0. - Review the evidence and your use of @openuidev/lang-core@0.3.0 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.
