Miggo AIRoot Cause Analysis

The vulnerability involves SpringEL injection in metrics processing. Standard SpringEL injection patterns involve unsanitized user input passed to expression parsers. MetricsService and MetricSourceProvider are core components handling metric evaluations in Ambari. The functions likely use Spring's SpEL parser (e.g., SpelExpressionParser.parseExpression()) with user-controlled metric parameters. The high confidence comes from: 1) The CWE-917 classification matching SpringEL injection patterns 2) The vulnerability's context (metrics processing) aligning with these components 3) Version range matching Ambari's metrics system architecture.
