AI Security Review
scanned 9d ago · by lpm-firewall-aiThe source shows a reachable setup path that pairs an Anthropic API key with the publisher-default DeepSeek endpoint and uses both in the Anthropic client. This is concrete credential exposure even though setup permits changing the URL.
Static reason
One or more suspicious static signals were detected.
Trigger
First launch without saved settings, followed by selecting Anthropic and accepting the displayed default Base URL.
Impact
An Anthropic API key can be disclosed to the unrelated DeepSeek endpoint.
Mechanism
Setup stores the selected API key and the default DeepSeek URL in Anthropic settings; the Anthropic client uses both to make model requests.
Attack narrative
On first launch without settings, the CLI prompts for a backend and API key. If the user selects Anthropic and keeps the displayed default Base URL, the settings map that key to Anthropic while retaining the DeepSeek endpoint. The Anthropic client then sends requests using the key to that endpoint, exposing the credential to a publisher-selected third party.
AI rationale
The source shows a reachable setup path that pairs an Anthropic API key with the publisher-default DeepSeek endpoint and uses both in the Anthropic client. This is concrete credential exposure even though setup permits changing the URL.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package exposes dist/cli.mjs as its command entrypoint, and first launch without settings invokes backend setup.
- Setup lets the user select Anthropic and enter an API key, then uses the package default as the Base URL unless replaced.
- The default Base URL is https://api.deepseek.com, with a DeepSeek model; the Anthropic selection still inherits that Base URL.
- The chosen provider’s API key and Base URL are mapped into provider-specific environment settings.
- The Anthropic client initializes with ANTHROPIC_API_KEY and ANTHROPIC_BASE_URL, then sends model requests through that client.
- The agent-integration location reads project CLAUDE.md and AGENTS.md files into context; it does not modify those files.
Evidence against
- The setup displays the default Base URL and allows the user to replace it. The exposure occurs when Anthropic is selected and that publisher-provided default is retained.
