Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 28 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.1.20 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface. Installation mutates only this package's launcher and adjacent vendor directory; runtime networking is package-aligned LLM/provider functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-25T12:51:41.579Z - **Finished:** 2026-08-25T12:52:55.622Z - **Download time:** 2091 ms - **Static scan time:** 13733 ms - **AI review time:** 58215 ms - **Total time:** 74043 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:** No confirmed malicious attack surface. Installation mutates only this package's launcher and adjacent vendor directory; runtime networking is package-aligned LLM/provider functionality. - **Trigger:** npm postinstall; CLI invocation for runtime provider, OAuth, and update features. - **Impact:** No unconsented foreign AI-agent control-surface mutation, credential exfiltration, remote payload execution, or destructive behavior was confirmed. - **Evidence paths:** package.json, install.cjs, cli-wrapper.cjs, bin/claudin.exe, dist/cli.mjs, dist/chunks/provider-1.1.20-x6r7w9y0.mjs, dist/chunks/startupUpdateCheck-1.1.20-na2gc2z0.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T12:52:55.622Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** same-package native launcher placement and user-invoked AI CLI functionality - **Rationale:** Direct inspection shows a same-package binary wrapper postinstall and a user-invoked LLM CLI, not a concrete malicious chain. Static hits for environment, network, and process APIs are explained by its provider/OAuth and launcher roles. - **Files touched:** bin/claudin.exe, bin/vendor, cli-wrapper.cjs, dist/cli.mjs ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence against:** postinstall only selects a same-vendor optional native binary and replaces the package's own bin/claudin.exe launcher., Postinstall copies only the native binary's vendored ripgrep beside that package launcher; it has no network, credential, or agent-config logic., The fallback launcher executes the selected same-vendor binary or bundled dist/cli.mjs., Bundled network code is provider/OAuth and update functionality activated during CLI runtime, not install-time harvesting., The ~/.claude to ~/.claudin migration is exposed as an explicit /provider migrate command. ## Affected versions and remediation This report applies to @claudiolabs/claudin@1.1.20. - Review the evidence and your use of @claudiolabs/claudin@1.1.20 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.
