It can cause installed AI coding clients to load package-provided skills and launch the Wowok MCP server. - **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:** 3.2.6 - **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. Installing the package automatically changes user-scoped AI-agent skill and MCP control surfaces. No user command is required for this behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-27T16:09:11.993Z - **Finished:** 2026-09-27T16:11:59.638Z - **Download time:** 756 ms - **Static scan time:** 475 ms - **AI review time:** 166413 ms - **Total time:** 167645 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:** Installing the package automatically changes user-scoped AI-agent skill and MCP control surfaces. No user command is required for this behavior. - **Trigger:** npm postinstall runs during package installation. - **Impact:** It can cause installed AI coding clients to load package-provided skills and launch the Wowok MCP server. - **Evidence paths:** package.json, scripts/install.js, dist/installer.js, dist/targets.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T16:11:59.638Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle installer selects default client targets, writes skills, installs or updates an MCP server, and registers its launcher in client configuration. - **Attack narrative:** A dependency installation triggers postinstall code. That code targets user-level AI-agent directories and MCP configuration, including Codex, and registers a launcher for a separate MCP server unless the user has pre-set an opt-out environment variable. This is an unconsented, automatic modification of broad agent control surfaces. - **Rationale:** The package performs automatic postinstall mutation of user-scoped AI-agent skill and MCP configuration, including a launcher registration. This meets the policy definition of a concrete foreign or broad AI-agent control-surface attack. - **Files touched:** package.json, scripts/install.js, dist/installer.js, dist/targets.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package declares an automatic postinstall lifecycle hook., The lifecycle entry point loads and invokes the installer., On postinstall, the installer resolves its default targets and installs files into user-scoped client locations., The target list includes Codex user skill and MCP configuration locations., Unless an environment opt-out is already set, postinstall manages an MCP server and registers it in client configuration files., The installer creates configuration directories and writes an MCP server entry containing a launcher command and arguments. - **Evidence against:** The MCP registration loop skips clients that are neither detected nor already configured., An environment variable can disable MCP management, but it is not enabled by default. ## Affected versions and remediation This report applies to @wowok/skills@3.2.6. - Avoid installing @wowok/skills@3.2.6. 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.
