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. The source confirms automatic vendor telemetry that can include personal Git identity and checkout information, creating a concrete privacy risk. The fixed package-aligned endpoint and opt-out reduce concern, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-10T03:29:46.318Z - **Finished:** 2026-10-10T03:30:20.960Z - **Download time:** 1290 ms - **Static scan time:** 253 ms - **AI review time:** 33098 ms - **Total time:** 34642 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:** Automatic installation telemetry sends an install event and available Git identity or checkout hints to the package vendor. This creates a conditional privacy exposure, but the inspected source does not show credential theft or a broader attack. - **Trigger:** Installing the package runs its postinstall lifecycle hook, unless collection is disabled by a recognized environment variable. - **Impact:** The vendor receives installation metadata and potentially personal Git identity and repository ownership information without an explicit interaction in the inspected install path. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-10T03:30:20.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector gathers installation identity, package and runtime details, and available Git name, email, and repository hints, then sends the event to a fixed HTTPS endpoint. - **Rationale:** The source confirms automatic vendor telemetry that can include personal Git identity and checkout information, creating a concrete privacy risk. The fixed package-aligned endpoint and opt-out reduce concern, so this warrants a warning rather than a block. - **Files touched:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs - **Network endpoints:** https://threadplane.ai/api/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest runs a postinstall script automatically, and that script invokes the collector when the lifecycle event is postinstall., The collector sends an install event by HTTPS POST to the fixed Threadplane endpoint., The event includes installation and package/runtime metadata, and attaches discovered Git identity when available., Git discovery reads global and consuming-checkout Git configuration; an environment opt-out disables collection. - **Evidence against:** The destination is a fixed vendor endpoint associated with the package, and the inspected collector does not forward credentials or follow redirects., Collection can be disabled with standard do-not-track variables or TPLANE\_TELEMETRY\_DISABLED. ## Affected versions and remediation This report applies to @threadplane/langgraph@0.3.0. - Review the evidence and your use of @threadplane/langgraph@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.
