Miggo AIRoot Cause Analysis

The vulnerability centers around improper privilege management during API key creation. Elasticsearch's API key generation logic (handled by ApiKeyService) is the primary suspect, as the advisory explicitly states the flaw occurs when attackers create API keys. The mitigation involves disabling API keys entirely, further implicating this component. While no direct code diffs are provided, the combination of the vulnerability description, CWE mapping to privilege assignment flaws, and standard Elasticsearch security architecture strongly points to the createApiKey method as the vulnerable entry point.
