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. An automatic postinstall collector reads available Git identity and installation context and sends an event to the vendor endpoint. This creates a conditional personal-data disclosure surface; no broader attack behavior was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-08T09:30:17.904Z - **Finished:** 2026-10-08T09:31:01.063Z - **Download time:** 1287 ms - **Static scan time:** 189 ms - **AI review time:** 41682 ms - **Total time:** 43159 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:** An automatic postinstall collector reads available Git identity and installation context and sends an event to the vendor endpoint. This creates a conditional personal-data disclosure surface; no broader attack behavior was established. - **Trigger:** Package installation runs the postinstall hook, unless collection is disabled or execution ends early. - **Impact:** Git display name or email and installation context may be disclosed to the vendor without an explicit opt-in. - **Evidence paths:** install/postinstall.cjs, install/collector.cjs, install/git-context.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-08T09:31:01.063Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector adds available Git identity to an installation event and posts it to the fixed vendor endpoint. - **Rationale:** The automatic postinstall collection of Git identity presents a real data-disclosure risk despite its vendor-aligned endpoint and opt-out controls. The inspected source does not establish a concrete malicious chain, so this warrants a warning rather than a publish 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:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall collector automatically., The collector sends installation data to the package vendor’s endpoint., The collector includes Git identity data, including the configured email, when available., The collector supports telemetry opt-out flags; the inspected source does not require opt-in. - **Evidence against:** The endpoint is on the package vendor’s domain and the collector accepts opt-out flags., The inspected code does not show credential collection, remote code execution, or destructive behavior. ## Affected versions and remediation This report applies to @threadplane/ag-ui@0.3.0. - Review the evidence and your use of @threadplane/ag-ui@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.
