@mutmutco/codex-plugin@4.5.144
MMI workflow skills and org gates delivery.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package has no install lifecycle script, and the flagged agent-directory code only classifies untracked Git paths. The CLI sends limited usage telemetry to its MMI Hub endpoint; the inspected telemetry path does not transfer credentials or command output.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running an mmi-cli command triggers the pre-action hook.
Impact
The inspected telemetry payload contains no credentials or command output, so no concrete attack impact was established.
Mechanism
The hook posts the command name, version, CI indicator, and operating system; telemetry can be disabled with MMI_TELEMETRY=off.
AI rationale
The package has no install lifecycle script, and the flagged agent-directory code only classifies untracked Git paths. The CLI sends limited usage telemetry to its MMI Hub endpoint; the inspected telemetry path does not transfer credentials or command output.

Decision evidence
public snapshotAI called this Clean at 82.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- package.json declares no lifecycle scripts and ships the plugin, skills, launcher, and CLI files.
- The flagged agent-directory code only classifies untracked Git paths; it does not mutate agent configuration.
- Each CLI command triggers telemetry containing the command, version, CI indicator, and operating system, with an opt-out; the destination is the MMI Hub endpoint.
Evidence against
- CLI usage telemetry is sent by default, but the inspected payload contains no credentials or command output.

Credential Exfiltration
Source appears to send environment or credential material to an external endpoint.
