It changes a foreign project AI-agent control surface without an explicit user command. - **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:** 2.0.0 - **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. Installation automatically modifies the consuming project's CLAUDE.md. The inserted content directs an AI agent to follow skills stored in this dependency. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-12T14:35:58.653Z - **Finished:** 2026-09-12T14:36:45.324Z - **Download time:** 504 ms - **Static scan time:** 423 ms - **AI review time:** 45743 ms - **Total time:** 46671 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:** Installation automatically modifies the consuming project's CLAUDE.md. The inserted content directs an AI agent to follow skills stored in this dependency. - **Trigger:** npm or pnpm installation triggers postinstall. - **Impact:** It changes a foreign project AI-agent control surface without an explicit user command. - **Evidence paths:** package.json, scripts/init-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T14:36:45.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic consumer AI-agent instruction-file mutation. - **Attack narrative:** When installed, npm runs scripts/init-skills.js. The script resolves the consumer project directory from INIT\_CWD, then creates or rewrites CLAUDE.md there. Its inserted block instructs an AI agent to read package-controlled skill files before using the library. This is an unconsented postinstall modification of a foreign AI-agent control surface. - **Rationale:** The automatic postinstall hook writes behavior-bearing instructions into the consuming project's CLAUDE.md. This is concrete install-hook abuse even though the inspected code does not show network exfiltration or shell execution. - **Files touched:** CLAUDE.md, scripts/init-skills.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs its initializer after installation., The initializer uses the consumer project root and targets its CLAUDE.md file., The initializer appends or replaces agent instructions that direct future use toward package-controlled skills. - **Evidence against:** No network access, shell execution, credential collection, or payload download appears in the inspected lifecycle code., The published runtime entrypoint is a component export bundle. ## Affected versions and remediation This report applies to elsan-puulse-react@2.0.0. - Avoid installing elsan-puulse-react@2.0.0. 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.
