A dependency install can change how local AI-agent tooling connects to remote services and launches commands. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.1.100 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation automatically alters broad AI-agent and project control surfaces. It installs MCP servers, including one that runs npx, into the consumer project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-07T15:13:09.107Z - **Finished:** 2026-09-07T15:14:10.703Z - **Download time:** 766 ms - **Static scan time:** 880 ms - **AI review time:** 59949 ms - **Total time:** 61596 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 alters broad AI-agent and project control surfaces. It installs MCP servers, including one that runs npx, into the consumer project. - **Trigger:** npm installation, which runs postinstall automatically. - **Impact:** A dependency install can change how local AI-agent tooling connects to remote services and launches commands. - **Evidence paths:** package.json, bin/install.js, bin/folder-mappings.js, mcp.json - **Review source:** ai\_review - **Reviewed:** 2026-09-07T15:14:10.703Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Recursive installation of agent configuration and MCP command definitions. - **Attack narrative:** On npm install, postinstall launches an installer without requiring an explicit setup command. The installer recursively writes package content into .claude, .gemini, .github, .vscode, and .mcp.json in the consuming project. Its MCP configuration adds remote services and an npx-based command, changing AI-agent control surfaces as a side effect of dependency installation. - **Rationale:** This is an unconsented postinstall mutation of broad AI-agent control surfaces in the consumer project. The automatic configuration includes remote MCP endpoints and a command launcher. - **Files touched:** package.json, bin/install.js, bin/folder-mappings.js, mcp.json - **Network endpoints:** https://platform-architecture-mcp-siesa-103767536676.us-east1.run.app/mcp, https://mcp.atlassian.com/v1/sse ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically runs the installer., The installer recursively overwrites project-wide Claude, Gemini, GitHub, VS Code, and MCP configuration paths., The installed MCP configuration registers remote servers and an npx command for agent tooling. - **Evidence against:** No runtime dependency on another release of this package is declared., The inspected installer does not contain credential exfiltration code. ## Affected versions and remediation This report applies to siesa-agents@2.1.100. - Avoid installing siesa-agents@2.1.100. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
