Miggo AIRoot Cause Analysis

The vulnerability stemmed from using broad wildcard patterns ('/cloudfoundryapplication/**') in security configurations rather than dynamically generated paths based on actual endpoints. The commit diff shows the fix replaced static path matchers with logic using PathMappedEndpoints to collect all endpoint paths, indicating the original static pattern matching in these security configuration handlers was the vulnerable code path. The affected functions handled security filter chain configuration for Cloud Foundry deployments.
