Future AI-agent sessions in the consumer project can be influenced to load the package's instruction material. - **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:** 2.0.3 - **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. An installation lifecycle hook modifies an AI-agent instruction file in the consuming project. This is an unconsented mutation of a foreign agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-29T07:19:52.010Z - **Finished:** 2026-09-29T07:20:38.966Z - **Download time:** 763 ms - **Static scan time:** 453 ms - **AI review time:** 45739 ms - **Total time:** 46956 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:** An installation lifecycle hook modifies an AI-agent instruction file in the consuming project. This is an unconsented mutation of a foreign agent control surface. - **Trigger:** Installing the package runs the post-install lifecycle hook. - **Impact:** Future AI-agent sessions in the consumer project can be influenced to load the package's instruction material. - **Evidence paths:** package.json, scripts/init-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T07:20:38.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook derives the consumer project root and writes or updates its Claude configuration file with package-provided instructions. - **Attack narrative:** Package installation automatically invokes a script that targets the consuming project's Claude configuration file. The script preserves or replaces a marked section and otherwise appends package-controlled agent instructions. It performs this project-level AI-agent configuration mutation without an explicit user command or consent prompt. - **Rationale:** The automatic post-install hook writes to a consumer-owned AI-agent control file, meeting the policy threshold for unconsented lifecycle mutation of a foreign control surface. No additional network or credential behavior is needed for this blocking finding. - **Files touched:** package.json, scripts/init-skills.js, CLAUDE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs the skills initializer after installation., The initializer resolves the consuming project directory from the package-manager install context., The initializer reads, replaces, or appends content in the consumer project's Claude configuration file without a consent gate. - **Evidence against:** No child-process execution, dynamic-code evaluation, or credential collection was found in the targeted inspection., The targeted script contains no network send operation. ## Affected versions and remediation This report applies to elsan-puulse-react@2.0.3. - Avoid installing elsan-puulse-react@2.0.3. 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.
