Any update on this? This topic explains the overall issue well (I see there are multiple threads on this issue), ie:
Get All Vulnerabilities In Environment API - InsightVM / API - Rapid7 Discuss
Connecting Vulnerabilities with Assets Through the InsightVM API? - InsightVM / API - Rapid7 Discuss
Seems like a major oversight that there is seemingly no way to “just” get a list of vulns in ones environment or even a specific site?
