Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe code creates a real unrestricted credential-forwarding capability, so it should warn. Static inspection did not establish malicious intent, a fixed exfiltration endpoint, or an install-time attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
An application invokes the exported AI chat or embedding client with an OpenAI or Anthropic provider, TINA4_AI_KEY set, and a custom AI endpoint.
Impact
A misconfigured or attacker-controlled environment variable can expose the provider API key to that endpoint.
Mechanism
Credential forwarding to an unrestricted configured AI URL.
AI rationale
The code creates a real unrestricted credential-forwarding capability, so it should warn. Static inspection did not establish malicious intent, a fixed exfiltration endpoint, or an install-time attack.
Evidence
package.jsonpackages/core/dist/index.jspackages/core/src/aiClient.ts
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package entrypoint is the bundled core module that contains the AI client.
- The AI client takes its API key from TINA4_AI_KEY while allowing TINA4_AI_URL to replace the provider endpoint without a host allowlist.
- For OpenAI and Anthropic modes, the client attaches that key to request headers and POSTs to the selected URL.
Evidence against
- The built-in provider defaults use the official OpenAI and Anthropic API hosts.
- The manifest has build-only prepare and prepublish hooks, not an automatic install or postinstall hook.
- No fixed unrelated recipient or hidden credential-export path was confirmed.
