Affected agents can load the package’s file-query tools in later sessions. - **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:** 1.0.5 - **Selected version is latest:** Yes - **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. Source confirms an automatic install hook that adds the package’s MCP server to multiple agent configuration surfaces without consent. This is an unconsented install-time AI-agent control-surface change. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-16T21:42:08.003Z - **Finished:** 2026-10-16T21:42:40.964Z - **Download time:** 511 ms - **Static scan time:** 92 ms - **AI review time:** 32357 ms - **Total time:** 32961 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:** Installation automatically changes global and project AI-agent settings to register the package’s MCP server. This creates an agent control surface without an explicit setup action or consent check. - **Trigger:** The package’s postinstall hook runs during installation. - **Impact:** Affected agents can load the package’s file-query tools in later sessions. - **Evidence paths:** package.json, scripts/install.js, mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T21:42:40.964Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer adds a local server entry to multiple agent configuration files when an entry for this package is absent; one entry is explicitly enabled. - **Attack narrative:** The postinstall hook writes MCP server registrations into global and project settings for several AI-agent tools without asking first. Those registrations point agents to this package’s file-query server. - **Rationale:** Source confirms an automatic install hook that adds the package’s MCP server to multiple agent configuration surfaces without consent. This is an unconsented install-time AI-agent control-surface change. - **Files touched:** package.json, scripts/install.js, mcp.js ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/install.js automatically after installation., The installer writes changed agent configuration files without prompting for consent., The installer adds the package’s MCP server to global and project agent settings when no existing entry is present., It also enables a global Kilo Code entry and adds entries to global and project Cursor settings., mcp.js exposes file-query tools to agents that load the server. ## Affected versions and remediation This report applies to @blazeinstall/hyperglob@1.0.5. - Avoid installing @blazeinstall/hyperglob@1.0.5. 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.
