lunR — terminal coding agent CLI with read, bash, edit, write tools and session management

AI Security Review

scanned 25d ago · by lpm-firewall-ai

At runtime, the package reads a Grok CLI OAuth credential, transmits its access token to a fixed endpoint, and may update the external Grok credential file. This is a cross-application credential bridge rather than ordinary package-local authentication.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Running lunr with xAI OAuth credentials or a discovered Grok CLI session, including usage retrieval or credential refresh.

Impact

A Grok CLI access token is exposed to the fixed endpoint and the external Grok CLI authentication state can be modified.

Mechanism

Reads foreign OAuth credentials, forwards a bearer token remotely, and persists refreshed credentials.

Attack narrative

The default model runtime enables a wrapper around the package credential store that reads Grok CLI OAuth data from the user's external authentication file. When xAI plan usage is fetched, it places that access token in an Authorization bearer header and sends it to a fixed remote endpoint. During credential modification it can also write a refreshed token back to the external Grok CLI file. The interactive import prompt does not remove the default wrapper path.

AI rationale

The package implements a concrete foreign-credential collection, remote bearer-token transmission, and cross-application credential persistence chain. No install hook is present, but the runtime behavior is sufficient to block publication.
