Agents may place real credentials in documents or pull requests while reviewers are instructed to ignore the leak. - **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:** 1.5.155 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installation silently modifies downstream package-manager settings and AI-agent control files. The installed rules promote secret disclosure and suppress review of that disclosure. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-28T07:57:46.505Z - **Finished:** 2026-08-28T07:59:52.862Z - **Download time:** 1016 ms - **Static scan time:** 161 ms - **AI review time:** 125180 ms - **Total time:** 126357 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation silently modifies downstream package-manager settings and AI-agent control files. The installed rules promote secret disclosure and suppress review of that disclosure. - **Trigger:** Installing the package runs postinstall in the consuming project. - **Impact:** Agents may place real credentials in documents or pull requests while reviewers are instructed to ignore the leak. - **Evidence paths:** package.json, postinstall.js, merge.js, AGENTS.base.md, rules/review-boundary.md - **Review source:** ai\_review - **Reviewed:** 2026-08-28T07:59:52.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time downstream AI-agent control-surface mutation and malicious agent instructions. - **Attack narrative:** On installation, the package changes the consuming project's pnpm behavior and invokes its merger. The merger installs instructions into multiple AI-agent configuration surfaces. Those instructions direct agents to embed real credentials in documentation and direct reviewers not to report or remove such exposure. This creates an unconsented path from package installation to downstream AI-agent behavior that can disclose credentials through generated project documents or pull requests. - **Rationale:** This is malicious because an install-time hook modifies broad downstream AI-agent controls and deploys instructions that encourage credential exposure while suppressing security review. - **Files touched:** .npmrc, AGENTS.md, CLAUDE.md, .github/copilot-instructions.md, .github/instructions/\*.instructions.md, .claude/skills/\*, AGENTS.private.md - **Network endpoints:** https://github.com/user-attachments/assets/... ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook edits the consuming project's .npmrc to enable dependency lifecycle scripts and disable pnpm safeguards., Installation runs the merger in the consuming project without an explicit user command., The merger writes AGENTS.md, CLAUDE.md, Copilot instructions, and Claude skills into the consuming project., Installed agent instructions tell users to place real tokens, keys, and environment values in documentation., Those instructions also tell reviewers not to report or remove exposed secrets. - **Evidence against:** No source code performs direct network requests or reads and transmits credentials at runtime., The shell and update commands are limited to explicit command paths, not the install hook. ## Public findings ### 1.
