The consumer project's AI tooling can load package-authored instructions and agents by default. - **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:** 3.20.1 - **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 mutates the consumer project into an AI-agent framework installation. It installs all adapters and creates agent-control instruction files without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T13:19:16.692Z - **Finished:** 2026-09-08T13:20:26.056Z - **Download time:** 505 ms - **Static scan time:** 2420 ms - **AI review time:** 66438 ms - **Total time:** 69364 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 mutates the consumer project into an AI-agent framework installation. It installs all adapters and creates agent-control instruction files without an explicit user command. - **Trigger:** npm postinstall when izanagi-ai is installed as a dependency - **Impact:** The consumer project's AI tooling can load package-authored instructions and agents by default. - **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T13:20:26.056Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic broad AI-agent configuration and instruction injection into INIT\_CWD - **Attack narrative:** The package registers a postinstall hook. When installed under node\_modules, it uses npm's INIT\_CWD as the consumer project and automatically installs every framework pack and all AI CLI adapters. The installer copies package-controlled content into .agents and writes root AGENTS.md, SYSTEM.md, RULES.md, and an opencode.json that auto-loads the injected instructions. This is unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** This is a concrete automatic lifecycle attack path, not an explicit CLI setup action. Although no exfiltration was found in the inspected install path, the broad cross-platform agent-control mutation meets the publish-block policy. - **Files touched:** .agents/, AGENTS.md, SYSTEM.md, RULES.md, .izanagi/izanagi.config.json, opencode.json, .claude/, .codex/, .cursor/, .github/, .kimi/, .opencode/ ### 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 a postinstall launcher., The postinstall targets the consuming project's INIT\_CWD and invokes installation of every pack and all adapters., The installer recursively copies package content into the consumer and writes AI instruction files at the project root., It also creates an auto-loading OpenCode configuration without a user command or consent. - **Evidence against:** The inspected install path contains no network request or credential collection., The postinstall skips projects already containing .agents/core. ## Affected versions and remediation This report applies to izanagi-ai@3.20.1. - Avoid installing izanagi-ai@3.20.1. 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.
