Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Remote Code Execution - **Selected version:** 0.1.15 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has no automatic consumer-install hook, so the source does not establish malicious installation-time behavior. However, opaque portal-controlled command execution and an unprompted global updater are concrete high-risk capabilities that warrant a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-13T03:12:44.489Z - **Finished:** 2026-09-13T03:13:54.709Z - **Download time:** 1027 ms - **Static scan time:** 132 ms - **AI review time:** 69060 ms - **Total time:** 70220 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 authenticated MCP installation request can cause the package to execute a shell command returned by its portal. A normal launcher invocation also performs a detached global update to the latest release. - **Trigger:** Invoke the launcher, or invoke its MCP install operation after authentication. - **Impact:** A compromised or malicious portal response can run arbitrary commands with the invoking user's privileges and install a newer package release. - **Evidence paths:** dist/index.js, dist/launcher.js, launcher.config.json - **Review source:** ai\_review - **Reviewed:** 2026-09-13T03:13:54.709Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Portal-supplied command execution and silent global self-update. - **Rationale:** The package has no automatic consumer-install hook, so the source does not establish malicious installation-time behavior. However, opaque portal-controlled command execution and an unprompted global updater are concrete high-risk capabilities that warrant a warning. - **Files touched:** dist/index.js, dist/launcher.js, launcher.config.json, ~/.salesbot/vault.key, ~/.salesbot/portal-token.enc - **Network endpoints:** https://app.ai-agentos.jp ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Published code is deliberately obfuscated before publishing, preventing meaningful user inspection., The MCP install operation sends requested data to the portal and executes a command supplied in the response., The launcher silently starts a detached global update to the latest package release when invoked., The launcher can fetch bundled MCP definitions and pass portal-provided package and environment data into Claude Code. - **Evidence against:** There is no consumer install, preinstall, or postinstall lifecycle hook; prepublishOnly runs only when publishing., The command execution path requires an authenticated MCP install request rather than package installation., The visible vault implementation stores user-provided secrets locally with encryption and restrictive file permissions. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.15. - Review the evidence and your use of @funny-booth/agent-core@0.1.15 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.
