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 active postinstall hook sends installation telemetry that can contain Git identity and a persistent identifier. Its package-aligned endpoint and opt-out reduce the evidence for malicious intent, but default install-time disclosure warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-10T03:29:52.208Z - **Finished:** 2026-10-10T03:30:45.923Z - **Download time:** 1295 ms - **Static scan time:** 261 ms - **AI review time:** 52157 ms - **Total time:** 53715 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 postinstall hook sends an installation event to the package’s own telemetry endpoint. The event may include a persistent installation identifier and Git identity; this is a privacy risk, but the inspected source does not establish malicious intent. - **Trigger:** Installing the package with lifecycle scripts enabled, unless telemetry is disabled. - **Impact:** Installation and developer identity information may be disclosed to the package publisher. - **Evidence paths:** package.json, install/postinstall.cjs, install/collector.cjs, install/git-context.cjs, install/policy.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-10T03:30:45.923Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The collector gathers installation and environment details, optionally adds Git identity discovered from configuration, then posts the event to threadplane.ai. - **Rationale:** The active postinstall hook sends installation telemetry that can contain Git identity and a persistent identifier. Its package-aligned endpoint and opt-out reduce the evidence for malicious intent, but default install-time disclosure warrants a warning. - **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:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest runs a postinstall script that starts the collector., The postinstall code invokes collection only when npm identifies the lifecycle as postinstall., The collector posts installation events to threadplane.ai., The event can include identity data discovered from Git configuration, including a Git email., Telemetry can be disabled with TPLANE\_TELEMETRY\_DISABLED or standard do-not-track variables. - **Evidence against:** The collector targets the package’s own domain and restricts collection to a set of Threadplane packages., The install event is skipped when the opt-out is enabled; the source does not show collection of credentials or arbitrary files. ## Affected versions and remediation This report applies to @threadplane/langgraph@0.3.2. - Review the evidence and your use of @threadplane/langgraph@0.3.2 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.

High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** install/git-context.cjs - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = @threadplane/ag-ui@0.2.0 matchedPath = install/git-context.cjs matchedIdentity = npm:QHRocmVhZHBsYW5lL2FnLXVp:0.2.0 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 9. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** types/threadplane-langgraph.d.ts - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```typescript matchType = previous_version_dangerous_delta matchedPackage = @threadplane/langgraph@0.2.0 matchedIdentity = npm:QHRocmVhZHBsYW5lL2xhbmdncmFwaA:0.2.0 similarity = 0.818 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 10.
