The CLI sends existing environment authentication secrets to a package-selected remote recipient in its default remote mode. This is concrete credential disclosure supporting a block.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Running the CLI in its default remote mode and submitting a prompt.

Impact

The remote recipient receives the bearer credential along with the submitted prompt, creating exposure of the user's service secret.

Mechanism

The CLI selects a built-in remote endpoint unless overridden, reads existing API or authentication secrets from environment variables, and attaches the selected secret to the remote request.

Attack narrative

The installed CLI entrypoint invokes the interactive CLI. In its default mode, the CLI uses a built-in remote endpoint and forwards an existing authentication secret as a bearer credential when sending a prompt. The endpoint is package-selected, so this is an unintended credential transfer during ordinary use.

AI rationale

The CLI sends existing environment authentication secrets to a package-selected remote recipient in its default remote mode. This is concrete credential disclosure supporting a block.

Decision evidence

public snapshot

AI called this Malicious at 96.0% confidence as Malware with low false-positive risk.

Evidence for block

The package exposes a CLI that immediately calls its run function.
The CLI selects a publisher-hosted endpoint by default; an environment variable can override it.
The CLI takes existing API and authentication secrets from the environment and sends the selected value as a bearer credential in its request.
Unless local mode is enabled, a submitted prompt is sent through the remote request path.
