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. Source inspection confirms automatic, default-on install telemetry that sends persistent and project-derived identifiers to a configured collector. The notice, opt-out flags, and package-specific event reduce concern, but do not make transmission affirmative opt-in. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-14T03:42:05.246Z - **Finished:** 2026-10-14T03:43:01.376Z - **Download time:** 770 ms - **Static scan time:** 1141 ms - **AI review time:** 54218 ms - **Total time:** 56130 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:** The install hook sends package telemetry automatically, including a persistent install ID and a salted project-derived identifier. This creates a conditional disclosure concern, though the code presents it as OpenUI Lang Core telemetry. - **Trigger:** Installing the package with telemetry disable flags unset. - **Impact:** The collector receives persistent installation and project-derived identifiers plus package, platform, and CI metadata. - **Evidence paths:** package.json, postinstall.cjs, dist/postinstall.cjs, dist/shared-BuVpfVsg.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-14T03:43:01.376Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall code derives a project identity, builds telemetry metadata, and posts it to the configured collector. - **Rationale:** Source inspection confirms automatic, default-on install telemetry that sends persistent and project-derived identifiers to a configured collector. The notice, opt-out flags, and package-specific event reduce concern, but do not make transmission affirmative opt-in. - **Files touched:** package.json, postinstall.cjs, dist/postinstall.cjs, dist/shared-BuVpfVsg.cjs - **Network endpoints:** https://dgoeivjus9jfp.cloudfront.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package postinstall hook loads telemetry code that runs automatically during installation., The telemetry includes a persistent random install ID and a salted hash derived from the install project's identity., Unless disabled by environment flags, the hook sends the payload in an HTTP POST to its configured collector., The default collector host is dgoeivjus9jfp.cloudfront.net. - **Evidence against:** The hook displays a telemetry notice and supports OPENUI\_TELEMETRY\_DISABLED=1 or DO\_NOT\_TRACK=1., The event and collected metadata are specific to OpenUI Lang Core installation telemetry. ## Affected versions and remediation This report applies to @openuidev/lang-core@1.0.0. - Review the evidence and your use of @openuidev/lang-core@1.0.0 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.
