AI Security Review
scanned 6d ago · by lpm-firewall-aiThe source confirms that a configured API URL receives the resolved credential in authenticated requests, without a destination restriction. The default is package-aligned and the custom URL is operator-configurable, so this warrants a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Run the server with a credential and configure CACHLY_API_URL or use the setup command’s --api-url option.
Impact
A custom endpoint can receive the Cachly credential in authenticated requests; the source does not restrict the destination to Cachly’s API.
Mechanism
The runtime builds requests from the configured API base and attaches the resolved credential as a Bearer token, including on telemetry error paths.
AI rationale
The source confirms that a configured API URL receives the resolved credential in authenticated requests, without a destination restriction. The default is package-aligned and the custom URL is operator-configurable, so this warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The runtime defaults its API base to api.cachly.dev but allows CACHLY_API_URL to replace it.
- The API client sends requests to that base with the resolved credential in a Bearer header.
- The autopilot command accepts an explicit --api-url value and applies it to the API base.
- Credentials can be resolved from environment variables or saved Cachly configuration.
- Two runtime error paths send authenticated telemetry requests to the configured API base.
Evidence against
- The default API host is the package’s Cachly service, and the custom URL can be explicitly supplied by the operator.
- The postinstall script prints setup guidance; it does not itself send credentials.
