Severity	Finding	Layer	Location
INFO	Potential Data Exfiltration via Environment Variable Access and External API Call The skill demonstrates accessing an environment variable (`POSTBRIDGE_API_KEY`) and sending it, along with potentially user-generated content, to an external service via an HTTP POST request. While the target URL is a placeholder (`https://your-crosspost-service.example/api/posts`), this pattern highlights a mechanism that could be used for data exfiltration if the target service is untrusted or if sensitive, unauthorized environment variables are accessed and transmitted. Ensure that any external services integrated are trusted and that API keys or other sensitive environment variables are only accessed and transmitted to authorized endpoints. Implement strict access controls for environment variables and validate all external URLs. For production environments, consider using a dedicated secrets management system instead of direct environment variables.	Static	SKILL.md:126
