BIM Engine SDK for Vue2, Vue3, React and HTML
AI Security Review
scanned 15h ago · by lpm-firewall-aiThe public encoding feature sends model properties to DeepSeek with a bundled key, without an evident user-configured service or key. The request is tied to an explicit feature call, so this is suspicious undisclosed external data handling rather than malicious automatic exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A caller invokes `oneClickEncoding.start()`.
Impact
Model properties are disclosed to an external AI service without an evident user-configured endpoint or key.
Mechanism
The method queries properties for matching model components, batches the results, and POSTs each batch to DeepSeek’s chat completions endpoint.
AI rationale
The public encoding feature sends model properties to DeepSeek with a bundled key, without an evident user-configured service or key. The request is tied to an explicit feature call, so this is suspicious undisclosed external data handling rather than malicious automatic exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The encoding feature defaults to a hard-coded API key and `https://api.deepseek.com`.
- Its `start()` method collects model component properties and passes them as JSON to the chat method.
- The chat method POSTs that content to DeepSeek using the API key in a Bearer header.
- The package’s type declarations expose `OneClickEncoding.start()` as a callable method.
- The engine constructor creates the encoding feature, while the network request is reached through its `start()` flow.
Evidence against
- The package scripts shown are development, build, and test commands; no install lifecycle script is declared.
- The source ties the external request to a feature for generating model encodings, rather than an install-time or import-time data collection flow.
