Miggo AIRoot Cause Analysis

The vulnerability stemmed from two key flaws: 1) SessionService::setAuthorizedBackendSession in vulnerable versions didn't persist critical backend user session metadata (user ID, session ID HMAC), making it impossible to later verify if the original backend session was still valid. 2) The Maintenance middleware didn't perform ongoing validation of backend user privileges/session status during requests. The fix added these validations by storing session references and implementing privilege checks in the middleware, confirming these were the missing security controls.
