Miggo AIRoot Cause Analysis

The vulnerability stems from missing session migration after remember-me authentication. The patch adds sessionStrategy->onAuthentication() in RememberMeListener::handle() to trigger session migration. In vulnerable versions, the absence of this session ID rotation in the handle() method allowed attackers to fixate sessions. The handle() method is the entry point for remember-me authentication processing and would appear in stack traces during exploitation.
