Package-controlled files can replace or add scripts and helpers in the consumer’s agent control surface. - **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:** 4.13.1 - **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. The npm postinstall bootstrap writes package scripts and helpers into an existing consumer .claude directory. This changes files used by the consumer’s AI-agent setup without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-10-07T21:58:13.950Z - **Finished:** 2026-10-07T21:58:50.448Z - **Download time:** 761 ms - **Static scan time:** 10355 ms - **AI review time:** 25379 ms - **Total time:** 36498 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:** The npm postinstall bootstrap writes package scripts and helpers into an existing consumer .claude directory. This changes files used by the consumer’s AI-agent setup without an explicit setup command. - **Trigger:** Installing the package in a project that already has a .claude directory. - **Impact:** Package-controlled files can replace or add scripts and helpers in the consumer’s agent control surface. - **Evidence paths:** package.json, scripts/post-install-bootstrap.mjs, bin/lib/shipped-scripts.json - **Review source:** ai\_review - **Reviewed:** 2026-10-07T21:58:50.448Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall bootstrap syncs shipped scripts into .claude/scripts and helpers into .claude/helpers. - **Attack narrative:** During npm installation, the package runs a postinstall bootstrap. If the consumer project has a .claude directory, the bootstrap syncs package scripts and helpers into .claude/scripts and .claude/helpers, including hook-related files listed in the shipped-file manifest. This is an automatic mutation of the consumer’s agent control surface. - **Rationale:** The manifest activates the bootstrap during npm postinstall, and source shows it copying package-controlled hook scripts and helpers into an existing consumer .claude directory. That unconsented control-surface mutation supports blocking. - **Files touched:** .claude/scripts/, .claude/helpers/ ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically runs the bootstrap during npm installation., When the consumer project has a .claude directory, the bootstrap copies package scripts and helpers into its control directories., The shipped-file manifest includes Claude hook scripts and helpers, and the bootstrap syncs these files into the consumer project., The package’s postinstall bootstrap is an unconsented mutation of the consumer’s AI-agent control surface. - **Evidence against:** The bootstrap skips projects without a .claude directory and skips installing into the package’s own source project., No credential theft or outbound exfiltration was established in the inspected behavior. ## Affected versions and remediation This report applies to moflo@4.13.1. - Avoid installing moflo@4.13.1. 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.
