Miggo AIRoot Cause Analysis

The GitHub commit diff shows the vulnerability was in _fnSetObjectDataFn where prototype pollution checks were incomplete. The patch adds 'constructor' to the blocked property names, confirming this was the vulnerable code path. The CVE description explicitly mentions this as an incomplete fix for a previous prototype pollution issue (CVE-2020-28458), and the function's purpose of processing object data makes it a clear vector for prototype pollution attacks when proper property validation is missing.
