AI Security Review

scanned 12d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. The package automatically modifies its bundled ACP dependency at installation and can create MCP extension configuration for Codex sessions. No confirmed malicious attack was identified.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

The postinstall lifecycle hook runs during installation; MCP configuration is used when the package runs a Codex session.

Impact

A configured MCP extension could receive powerful agent execution capability. The inspected code scopes Codex state to a per-profile directory, but the provenance and validation of supplied MCP server objects were not established.

Mechanism

The hook patches a dependency file. The runner accepts MCP server URLs, headers, commands, arguments, and environment values when composing session configuration.

AI rationale

This is not concrete malware, but automatic dependency mutation combined with configurable MCP command and endpoint setup creates a guarded agent-extension risk. No source fact established exfiltration, destructive behavior, or a hidden recipient.
