Miggo AIRoot Cause Analysis

The stack trace shows repeated calls to GetJSONValueRecursive and GetJSONArray when processing nested structures. The vulnerability manifests in recursive parsing functions that lack depth tracking or cycle detection. These functions create new stack frames for each nested element without limit, making them directly responsible for stack exhaustion. The PoC demonstrates this by generating a deeply nested JSON array that triggers a StackOverflowError through recursive parsing.
