AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, unconsented postinstall mutation of a consuming project's AI-agent control files. The behavior meets the blocking policy regardless of the absence of credential exfiltration.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm install of the package as a dependency inside node_modules
Impact
Hijacks or alters Codex, Claude Code, and Cursor instruction surfaces so future agent sessions follow package-supplied guidance.
Mechanism
postinstall writes AI-agent control stubs into the consumer project root
Policy narrative
On dependency installation, the postinstall script identifies the consumer project root via INIT_CWD and detects AI-agent environment variables. If no agent signal exists, it defaults to all targets and creates or merges package-authored instructions into AGENTS.md, CLAUDE.md, and .cursorrules. Those files direct future coding agents to read the installed package's operating contract before making code changes, modifying a broad foreign AI-agent control surface without an explicit user command.
AI rationale
This is a concrete, unconsented postinstall mutation of a consuming project's AI-agent control files. The behavior meets the blocking policy regardless of the absence of credential exfiltration.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 99.0% confidence with low false-positive risk.
Evidence for policy risk
- `package.json` runs `node postinstall.js` on installation.
- `postinstall.js` targets `INIT_CWD` or the consumer project root.
- `postinstall/detect-agent.js` defaults to `all` when no agent is detected.
- `postinstall.js` writes project-root `AGENTS.md`, `CLAUDE.md`, and `.cursorrules`.
- `postinstall/agent-stubs.js` injects instructions directing AI agents to package-controlled documentation.
Evidence against
- No credential harvesting, exfiltration, or network request was found in the inspected postinstall path.
- CLI shell/package-manager actions are user-invoked commands, not triggered by installation.
