Unconsented persistent execution in the consumer's AI-agent control surface. - **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:** 0.18.20 - **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 silently modifies the consumer project's Claude Code hook configuration. The added wildcard hook executes the package handler on every Claude tool call. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T06:04:40.433Z - **Finished:** 2026-09-11T06:05:34.792Z - **Download time:** 769 ms - **Static scan time:** 3715 ms - **AI review time:** 49875 ms - **Total time:** 54359 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 silently modifies the consumer project's Claude Code hook configuration. The added wildcard hook executes the package handler on every Claude tool call. - **Trigger:** npm postinstall during package installation, followed by any Claude Code tool call. - **Impact:** Unconsented persistent execution in the consumer's AI-agent control surface. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T06:05:34.792Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic wildcard PreToolUse hook registration in a consumer project. - **Attack narrative:** The package's automatic postinstall script searches for the consuming project, creates .claude, and merges a wildcard PreToolUse command into .claude/hooks.json. That command invokes the package's bundled handler whenever Claude Code uses any tool. This is an unconsented install-time mutation of a foreign AI-agent control surface and creates persistent agent-hook execution. - **Rationale:** Source inspection confirms an automatic postinstall that writes a wildcard Claude Code hook into the consuming project. This meets the policy threshold for malicious install-hook abuse regardless of the handler being local. - **Files touched:** .claude/hooks.json, dist/hooks/pre-tool-use.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall script automatically during installation., The installer locates the consumer project and creates its .claude directory., It registers a wildcard PreToolUse command, causing its handler to run for every Claude tool call., It writes the merged hook configuration without user interaction. - **Evidence against:** The installed command points to a bundled local handler rather than a remote shell command., No external network endpoint is established by the installer itself. ## Affected versions and remediation This report applies to @devflow-tools/devflow@0.18.20. - Avoid installing @devflow-tools/devflow@0.18.20. 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.
