Installation can cause Codex and other AI clients to load package-provided skills and a registered MCP server in their user configuration. - **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:** 3.2.2 - **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. An npm postinstall automatically modifies user-level AI-agent skill and MCP control surfaces across client targets. No explicit user command is required. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-20T06:44:41.085Z - **Finished:** 2026-09-20T06:53:47.310Z - **Download time:** 512 ms - **Static scan time:** 305 ms - **AI review time:** 545407 ms - **Total time:** 546225 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 npm postinstall automatically modifies user-level AI-agent skill and MCP control surfaces across client targets. No explicit user command is required. - **Trigger:** Installing the package through npm triggers postinstall. - **Impact:** Installation can cause Codex and other AI clients to load package-provided skills and a registered MCP server in their user configuration. - **Evidence paths:** package.json, scripts/install.js, dist/installer.js, dist/targets.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T06:53:47.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher calls the lifecycle handler, which resolves all targets, writes user-scope skills, installs or manages an MCP server, and registers it in client configuration files unless a pre-set environment opt-out is present. - **Attack narrative:** The package manifest automatically launches an installer on npm postinstall. That installer selects all supported clients by default, writes skills into user-controlled agent directories, and registers an MCP server in client configuration files. Codex is explicitly among the targets, including its user skill directories and MCP configuration. The environment opt-out requires prior user knowledge and does not make the default lifecycle behavior consented. - **Rationale:** This is a concrete unconsented postinstall mutation of broad, foreign AI-agent control surfaces. It meets the install-control-surface blocking policy even though no secret exfiltration was found. - **Files touched:** scripts/install.js, dist/installer.js, dist/targets.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs a postinstall launcher., The launcher invokes the lifecycle handler during npm installation., The postinstall handler targets every client, writes user-scope skills, and registers an MCP server unless an environment opt-out is set., The target definitions include Codex user skill directories and its user MCP configuration file. - **Evidence against:** No credential harvesting or direct data-exfiltration sink was identified in the inspected lifecycle path., The MCP command is a named package rather than an embedded opaque payload. ## Affected versions and remediation This report applies to @wowok/skills@3.2.2. - Avoid installing @wowok/skills@3.2.2. 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.
