Miggo AIRoot Cause Analysis

The vulnerability stemmed from how the 'try' authentication mode was handled. The code path for missing tokens in non-'required' modes (like 'try') returned empty credentials while still marking the request as authenticated. This was fixed in 5.1.2 by removing the early return that set empty credentials, ensuring proper authentication checks. The GitHub issue #111 and PR #112 demonstrate this logic flaw in the authentication handler function().
