MindExec local runtime and bridge CLI

AI Security Review

scanned 12h ago · by lpm-firewall-ai

The package is a local AI bridge with dangerous user-invoked capabilities, not confirmed malware. Runtime APIs can execute shell commands, run Codex, proxy remote device control, and expose an externally reachable RemoteHub gated by a pairing token.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs mindexec/mind-bridge or node server.js; postinstall only prepares grammars.

Impact

If exposed or token-compromised, an attacker could run commands or control paired remote agents; no unconsented install-time hijack was found.

Mechanism

localhost bridge plus paired remote-agent hub with shell/Codex execution APIs

Attack narrative

Runtime starts a local bridge and RemoteHub. Authenticated local routes can execute shell commands and run Codex tasks, while paired remote agents can receive input/task commands. These are product-aligned remote/AI orchestration capabilities activated by running the CLI, not by package install.

Rationale

Static inspection shows a legitimate but high-risk local AI/remote-control bridge; the install hook is limited to grammar setup and does not plant foreign agent configuration or persistence. The remaining risk is dangerous capability exposure if the runtime or pairing token is reachable.

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for block

server.js exposes token-gated local APIs for shell execution and Codex task execution.
remote-hub.js starts a RemoteHub on 0.0.0.0:5199 by default with pair-token authentication.
codex-runtime.js can create isolated CODEX_HOME under ~/.mindexec/codex-runtime and launch Codex SDK/CLI on API request.
server.js /api/status returns bridgeToken, but HTTP server binds to 127.0.0.1 only.

Evidence against

package.json postinstall only runs scripts/setup-tree-sitter-grammars.mjs to copy packaged tree-sitter WASM files into tree-sitter-grammars.
No install-time writes to foreign AI-agent control surfaces such as .mcp.json, CLAUDE.md, Cursor, or user Codex config by default.
launch-bridge.cjs is user-invoked CLI startup; it spawns server.js and optionally opens localhost app.
No credential exfiltration or remote payload download found in inspected entrypoints.
