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 postinstall path performs automatic identifiable telemetry, including available Git identity, with an opt-out instead of affirmative consent. The endpoint appears brand-aligned, so the source supports a privacy risk warning but does not establish a malicious unrelated-recipient attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-24T05:57:39.230Z - **Finished:** 2026-10-24T05:58:28.239Z - **Download time:** 767 ms - **Static scan time:** 275 ms - **AI review time:** 47965 ms - **Total time:** 49009 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:** Installation automatically sends an installation event and available Git identity data to a fixed Threadplane endpoint. This creates an identifiable install telemetry risk, though the inspected source does not establish an unrelated recipient. - **Trigger:** The package manager runs the package's postinstall lifecycle hook. - **Impact:** The recipient may associate installations with a persistent identifier and available Git display name or email. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/identity.cjs, install/git-context.cjs, install/policy.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-24T05:58:28.239Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector gathers installation and Git context, then posts the event unless a tracking-related environment variable disables collection. - **Rationale:** The postinstall path performs automatic identifiable telemetry, including available Git identity, with an opt-out instead of affirmative consent. The endpoint appears brand-aligned, so the source supports a privacy risk warning but does not establish a malicious unrelated-recipient attack. - **Files touched:** install/postinstall.cjs, install/collector.cjs, install/identity.cjs, install/git-context.cjs - **Network endpoints:** https://threadplane.ai/api/growth/collect/v1/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest runs install/postinstall.cjs after installation., The postinstall handler invokes the install collector when the lifecycle event is postinstall., The collector creates or reuses a persistent installation ID in the user's home directory., Git context collection includes configured display name and email when available., The collector sends an installation event and available identity data in a POST to a fixed Threadplane endpoint., Collection can be disabled with tracking-related environment variables, but otherwise runs without an affirmative opt-in. - **Evidence against:** The endpoint uses the same Threadplane brand as the package, so the inspected source does not establish an unrelated recipient., The collector has a disable flag and bounds execution time; its presence alone does not establish malicious intent. ## Affected versions and remediation This report applies to @threadplane/langgraph@0.3.3. - Review the evidence and your use of @threadplane/langgraph@0.3.3 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.
