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. LPM treats this as warn-only first-party agent extension lifecycle risk. A normal Claudin CLI startup can invoke bundled automatic marketplace-install logic. Package installation itself replaces only its own launcher with a platform binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-13T04:45:05.765Z - **Finished:** 2026-09-13T04:46:27.588Z - **Download time:** 1004 ms - **Static scan time:** 6728 ms - **AI review time:** 74090 ms - **Total time:** 81823 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:** A normal Claudin CLI startup can invoke bundled automatic marketplace-install logic. Package installation itself replaces only its own launcher with a platform binary. - **Trigger:** Installing the package runs postinstall; running the CLI can activate marketplace setup. - **Impact:** May add marketplace extensions and persist related state without a per-install user prompt; no confirmed secret theft or remote code execution was found. - **Evidence paths:** package.json, install.cjs, dist/chunks/cli-1.1.27-p99q7a22.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T04:46:27.588Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic launcher replacement and runtime marketplace installation. - **Rationale:** The automatic marketplace installation creates a real agent-extension lifecycle risk, but source inspection did not establish the concrete malicious chain required for a publish block. - **Files touched:** bin/claudin.exe, dist/chunks/cli-1.1.27-p99q7a22.mjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Installation automatically runs a launcher-replacement script., The bundled CLI contains an automatic official-marketplace installation path that persists retry state and can install extensions during normal startup. - **Evidence against:** The postinstall script only selects a platform optional dependency and replaces this package's bin/claudin.exe launcher., No source-confirmed credential exfiltration, remote payload download, self-dependency, or broad install-time agent-control mutation was found. ## Affected versions and remediation This report applies to @claudiolabs/claudin@1.1.27. - Review the evidence and your use of @claudiolabs/claudin@1.1.27 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.
