Unconsented mutation of a foreign AI-agent project control surface - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.33.1 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Install-time code offers a default-accepted copy of Claude control files into a path outside the installed package. The root calculation is flawed but can still target a parent project with package.json. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 91.0% - **Started:** 2026-08-08T21:59:42.543Z - **Finished:** 2026-08-08T22:00:46.725Z - **Download time:** 759 ms - **Static scan time:** 722 ms - **AI review time:** 62699 ms - **Total time:** 64182 ms ## Security analysis ### Published attack-surface review - **Summary:** Install-time code offers a default-accepted copy of Claude control files into a path outside the installed package. The root calculation is flawed but can still target a parent project with package.json. - **Trigger:** npm postinstall with an empty or affirmative prompt response - **Impact:** Unconsented mutation of a foreign AI-agent project control surface - **Evidence paths:** package.json, bin/postinstall.js, templates/kickstart/CLAUDE.md, templates/kickstart/.claude/settings.json - **Review source:** ai\_review - **Reviewed:** 2026-08-08T22:00:46.725Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** copies CLAUDE.md and .claude configuration into an external project - **Attack narrative:** Installing the package executes postinstall. Outside CI, it prompts to copy AI-assistance files and treats an empty response as acceptance; if its computed external target contains package.json, it creates CLAUDE.md and .claude/ there when absent. The shipped configuration is benign-looking framework guidance, and no exfiltration was found, but install-time mutation of a foreign Claude project surface is concrete. - **Rationale:** The package has a concrete npm postinstall path that can mutate foreign Claude control files without affirmative consent. This meets the install-control-surface block policy despite the flawed target-root calculation and benign template contents. - **Files touched:** CLAUDE.md, .claude/, blueprints/, types/ ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js on install., bin/postinstall.js defaults an install-time prompt to copying CLAUDE.md and .claude/., Writes target an external project path when its flawed root check succeeds., templates/kickstart/.claude/settings.json configures Claude project guidance. - **Evidence against:** Copied Claude files contain framework conventions, not credential theft or remote execution., No network, shell, or process execution occurs in bin/postinstall.js., CLI setup-ai performs the same operation after an explicit command and prompt. ## Public findings ### 1.
