The package can alter the instructions used by an AI agent in every consuming project without an explicit setup 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:** 2.0.1 - **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 automatically modifies the consumer project's CLAUDE.md, an AI-agent instruction file. The added instructions point the agent at package-controlled skill files. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-11T04:33:04.702Z - **Finished:** 2026-09-11T04:33:52.712Z - **Download time:** 502 ms - **Static scan time:** 841 ms - **AI review time:** 46667 ms - **Total time:** 48010 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 automatically modifies the consumer project's CLAUDE.md, an AI-agent instruction file. The added instructions point the agent at package-controlled skill files. - **Trigger:** npm or pnpm installation runs the postinstall hook. - **Impact:** The package can alter the instructions used by an AI agent in every consuming project without an explicit setup command. - **Evidence paths:** package.json, scripts/init-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T04:33:52.712Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall mutation of a consumer AI-agent control file. - **Attack narrative:** The manifest automatically launches scripts/init-skills.js after installation. That script resolves the consumer project directory, reads its CLAUDE.md, and either replaces a marked section or appends a new one. The inserted section instructs an AI agent to read package-owned skill files before using the library. This is an unconsented install-time write to a foreign AI-agent control surface, even though the inspected script does not exfiltrate data or contact a network service. - **Rationale:** The concrete postinstall write to the consumer's CLAUDE.md meets the policy for unconsented mutation of a foreign AI-agent control surface. The absence of observed network or credential behavior does not remove that install-time control risk. - **Files touched:** scripts/init-skills.js, CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its installer automatically through postinstall., The installer chooses the consuming project root from INIT\_CWD or the current directory., It creates or rewrites the consumer project's CLAUDE.md., The inserted content directs an AI agent to read package-provided skill instructions before use. - **Evidence against:** No source evidence of network requests, credential harvesting, shell execution, or payload download was found in the inspected lifecycle script., The published components entrypoint is a static export barrel, and the manifest has no dependency on this package itself. ## Affected versions and remediation This report applies to elsan-puulse-react@2.0.1. - Avoid installing elsan-puulse-react@2.0.1. 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.
