Future agent sessions receive a package-provided tool server through an installation-time configuration change that the user did not explicitly authorize. - **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:** 4.20.1 - **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. An automatic npm postinstall hook changes global Claude Code and Codex control surfaces. It registers the package's MCP server without requesting consent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T22:46:39.720Z - **Finished:** 2026-09-30T22:47:55.013Z - **Download time:** 1035 ms - **Static scan time:** 3438 ms - **AI review time:** 70819 ms - **Total time:** 75293 ms The recorded confidence comes from the underlying analysis.

It registers the package's MCP server without requesting consent. - **Trigger:** npm installation with lifecycle scripts enabled. - **Impact:** Future agent sessions receive a package-provided tool server through an installation-time configuration change that the user did not explicitly authorize. - **Evidence paths:** package.json, scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T22:47:55.013Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook reads global agent configuration, inserts server launch settings, and writes both files unconditionally. - **Attack narrative:** Installing the package activates its postinstall script. The script locates global Claude Code and Codex configuration files under the user's home directory, registers a command launching its MCP server, and persists both changes. No prompt, saved consent preference, or opt-in gate controls these calls. Although the server is package-owned, the destinations are broad control surfaces belonging to other agents. - **Rationale:** The source proves unconsented npm postinstall mutation of foreign, global AI-agent control surfaces, which meets the supplied blocking rule. This decision rests on the active installation chain, not citation limits or inferred credential theft. - **Files touched:** .claude.json, .codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs scripts/postinstall.js during npm installation., The postinstall hook targets the user's global .claude.json and .codex/config.toml files., The hook adds a Claude MCP server launch command and writes the changed configuration., The hook writes an MCP configuration block into Codex's global configuration., The active installation flow invokes both configuration mutations without a consent prompt or opt-in gate. - **Evidence against:** The registered server belongs to this package, and the hook preserves unrelated configuration entries., The inspected hook does not establish credential exfiltration or remote payload execution. ## Affected versions and remediation This report applies to karajan-code@4.20.1. - Avoid installing karajan-code@4.20.1. 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.
