Unconsented modification of a foreign project’s AI-agent configuration and future commit execution path. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.14 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package silently scaffolds an AI-agent/tooling control surface into the consumer project and changes its Git hook configuration. The resulting hook persists after installation and runs package-supplied code on commits. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 95.0% - **Started:** 2026-08-08T11:23:57.976Z - **Finished:** 2026-08-08T11:24:48.780Z - **Download time:** 506 ms - **Static scan time:** 350 ms - **AI review time:** 49947 ms - **Total time:** 50804 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package silently scaffolds an AI-agent/tooling control surface into the consumer project and changes its Git hook configuration. The resulting hook persists after installation and runs package-supplied code on commits. - **Trigger:** npm postinstall during package installation, including non-interactive installs. - **Impact:** Unconsented modification of a foreign project’s AI-agent configuration and future commit execution path. - **Evidence paths:** package.json, bin/install-host.js, scripts/setup/install-project-hooks.ps1, .vscode/mcp.json, .githooks/post-commit, scripts/ops/post-commit-refresh.ps1 - **Review source:** ai\_review - **Reviewed:** 2026-08-08T11:24:48.780Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** host-project MCP/agent configuration injection plus Git hook persistence - **Attack narrative:** On npm postinstall, the package uses the install working directory as a target, copies its agent instructions, MCP configuration, scripts, and Git hook files into that foreign project, then configures core.hooksPath. This occurs automatically in non-interactive installs and establishes package-controlled commands and a post-commit execution path without an explicit user setup command. - **Rationale:** Direct source inspection confirms unconsented postinstall mutation of a consumer project’s broad AI-agent control surface and persistent Git configuration. The overwrite guard does not mitigate creation of absent control files. - **Files touched:** package.json, bin/install-host.js, AGENTS.md, .vscode/mcp.json, .github/, .githooks/, scripts/setup/install-project-hooks.ps1, .githooks/post-commit, scripts/ops/post-commit-refresh.ps1, repo-registry/repos.yml ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/install-host.js via postinstall., bin/install-host.js copies AGENTS.md, .vscode, .github, scripts, and .githooks into the install host., Non-interactive postinstall initializes a host repo registry and invokes install-project-hooks.ps1., scripts/setup/install-project-hooks.ps1 sets the host repository's core.hooksPath to .githooks., Copied .vscode/mcp.json configures multiple MCP server commands in the host project., Copied post-commit hook invokes package-supplied PowerShell after future commits. - **Evidence against:** Lifecycle copying avoids overwriting existing files unless --force is supplied., No hard-coded network endpoint or credential exfiltration was found in the automatic postinstall path. ## Public findings ### 1.

Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** bin/install-host.js - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L28: "tooling", L29: "AGENTS.md", L30: "ARCHITECTURE.md", ...
