MindExec local runtime and bridge CLI

AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. No confirmed malicious install-time payload was found, but the package is a powerful local AI bridge. Runtime use exposes workspace file mutation, shell execution, Codex execution, and a default externally reachable RemoteHub guarded by pairing tokens.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

user runs mindexec or mind-bridge after install

Impact

authorized or locally token-acquiring clients can run commands and mutate workspace files; paired remote agents can receive tasks and input events

Mechanism

token-gated local bridge plus remote control hub

Rationale

Static inspection does not support a malicious verdict because the postinstall hook is limited to grammar setup and the dangerous primitives are declared runtime bridge features. The default RemoteHub and token-bearing local bridge are high-risk dual-use agent infrastructure, so warn rather than block.

Decision evidence

public snapshot

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

Evidence for warning

server.js exposes protected local file write/delete and shell execution APIs under /api/file/* and /api/shell/*.
server.js returns bridgeToken from unauthenticated /api/status, so local web clients can obtain the token for protected routes.
remote-hub.js starts a TCP RemoteHub on 0.0.0.0 by default with pair-token based remote device/control flows.
codex-runtime.js can spawn Codex and creates an isolated ~/.mindexec/codex-runtime with copied auth.json when user invokes Codex runs.
package ships native remote-fast binaries and wasm grammars.

Evidence against

package.json postinstall only runs scripts/setup-tree-sitter-grammars.mjs to copy packaged tree-sitter wasm files.
server.js binds the HTTP LocalBridge to 127.0.0.1, not a public interface.
Dangerous file/shell/Codex capabilities are runtime API features aligned with a local bridge/AI automation tool, not install-time execution.
Path validation confines file operations to the configured workspace or opened project root.
No credential harvesting or exfiltration endpoint was found in inspected source.
