This changes a separate AI agent's configuration and capabilities during package installation. - **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:** 3.7.0 - **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. The npm postinstall silently configures Claude Code for users who already have Claude installed. It adds MCP servers and changes agent permissions, plugins, and status-line behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-07T19:21:46.908Z - **Finished:** 2026-10-07T19:22:21.992Z - **Download time:** 770 ms - **Static scan time:** 320 ms - **AI review time:** 33992 ms - **Total time:** 35084 ms The recorded confidence comes from the underlying analysis.

It adds MCP servers and changes agent permissions, plugins, and status-line behavior. - **Trigger:** Installing the package with lifecycle scripts enabled when ~/.claude.json exists. - **Impact:** This changes a separate AI agent's configuration and capabilities during package installation. - **Evidence paths:** package.json, scripts/postinstall.js, src/utils/util-claude-config.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T19:22:21.992Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall calls the configuration routine, which updates Claude configuration files and copies a status-line script into ~/.claude without asking for consent. - **Attack narrative:** Package installation invokes Claude configuration automatically. If Claude Code is present, the routine updates MCP servers and settings, enables plugins and permissions, and installs a status-line script, changing an external agent's configuration without an explicit setup action. - **Rationale:** The install hook silently modifies Claude Code configuration and capabilities when Claude is detected, which is an unconsented install-time change to an AI-agent control surface. This supports blocking despite the configuration being limited to users with Claude installed. - **Files touched:** scripts/postinstall.js, src/utils/util-claude-config.js, ~/.claude.json, ~/.claude/settings.json, ~/.claude/statusline.js - **Network endpoints:** https://mcp-doc-framework-spring.preventsenior.com.br/externo/mcp, https://mcp-doc-framework-angular.preventsenior.com.br/externo/mcp, https://mcp-jira.preventsenior.com.br/externo/mcp, https://mcp-grafana.preventsenior.com.br/externo/mcp, https://preventsenior-swagger-dev.preventsenior.com.br/externo/mcp, https://mcp-bitbucket.preventsenior.com.br/externo/mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json defines a postinstall hook and a runtime dependency on the package itself., The postinstall script automatically calls the Claude configuration routine without a consent step., When Claude Code is present, the routine writes MCP server configuration and changes Claude settings, including permissions, enabled plugins, and the status line., The status line script is copied into the user's .claude directory; the cited completion code only adds PVS shell completion to a shell profile. - **Evidence against:** Claude configuration is gated on the presence of the user's .claude.json file., The configured MCP endpoints are Prevent Senior services, and the status line is installed as a local script. ## Affected versions and remediation This report applies to @preventsenior/pvs-cli@3.7.0. - Avoid installing @preventsenior/pvs-cli@3.7.0. 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.
