oh-my-codex@0.21.11
Multi-agent orchestration layer for OpenAI Codex CLI
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe default-enabled project hook mechanism can execute project-supplied code with the CLI process environment, so a capability warning is appropriate. The inspected lifecycle hook is limited to global-install hydration and a user install stamp, and the source does not establish a malicious attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A runtime hook event is dispatched while the current project contains an .omx/hooks plugin and plugins are enabled.
Impact
A project hook can run code with the CLI process privileges and environment, creating risk when a project contains an untrusted plugin.
Mechanism
The package starts a child process that imports the discovered plugin module and invokes its event handler; the child inherits the process environment.
AI rationale
The default-enabled project hook mechanism can execute project-supplied code with the CLI process environment, so a capability warning is appropriate. The inspected lifecycle hook is limited to global-install hydration and a user install stamp, and the source does not establish a malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The hook loader discovers project-local plugins under .omx/hooks, and runtime dispatch enables plugins by default unless disabled through an environment setting.
- When an event is dispatched, the package runs each discovered plugin in a child process that inherits the process environment; the runner imports the plugin and calls its event handler.
- The CLI provides an explicit command that creates a sample project hook. Existing hooks can also be discovered and run during runtime event dispatch.
- The postinstall hook invokes a routine that skips local installs; global installs perform native runtime hydration and update a user install stamp.
- The inspected agent-integration targets cover test fixtures and configuration-reading code; they do not establish additional install-time agent configuration mutation.
Evidence against
- The hook behavior is a runtime extension feature, not an install-time action; the sample hook is created by an explicit CLI command.
- The inspected postinstall routine does not configure agent hooks or plugins.
