## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Agents reading the project instructions are directed to adopt package-supplied skill rules.

- **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:** 2.0.4
- **Selected version is latest:** Yes
- **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 automatic postinstall script modifies the consuming project's CLAUDE.md without consent. This changes a project-wide AI-agent control surface.

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 automatic postinstall script modifies the consuming project's CLAUDE.md without consent. This changes a project-wide AI-agent control surface.

- **Trigger:** Installing the package in a consuming project with lifecycle scripts enabled.

- **Impact:** Agents reading the project instructions are directed to adopt package-supplied skill rules.

- **Evidence paths:** package.json, scripts/init-skills.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-30T08:18:26.285Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The script locates the consumer project, then appends package instructions or replaces an existing marked block in CLAUDE.md.

- **Attack narrative:** Installation automatically invokes the skill setup script. It uses the consumer project directory to locate CLAUDE.md and writes instructions requiring agents to consult package-owned rules. Neither creating the file nor updating its marked block requires consent. The library-specific content does not change the fact that installation mutates a broader project agent control surface.

- **Rationale:** The inspected postinstall path performs unconsented mutation of the consumer project's AI-agent instructions. This meets the supplied blocking rule for automatic lifecycle writes to a foreign or broad agent control surface.

- **Files touched:** CLAUDE.md

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for policy risk:** package.json automatically runs scripts/init-skills.js after installation., The script selects the consuming project using INIT\_CWD or the current directory., The script reads the project's CLAUDE.md and replaces or appends instructions without requesting consent., The inserted instructions require agents to read the package's skill rules before using its library.

- **Evidence against:** The inserted instructions concern the package's own UI library, and the script skips installation within the package itself.

## Affected versions and remediation

This report applies to elsan-puulse-react@2.0.4.

- Avoid installing elsan-puulse-react@2.0.4. 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.
