Miggo AIRoot Cause Analysis

The vulnerability centers on insufficient session invalidation. Magento's session termination mechanisms during logout/password changes are prime suspects. The Session::logout() method and its caller in the Logout controller are critical points where improper session handling (e.g., missing session regeneration or cookie invalidation) could leave sessions active. While exact patch details are unavailable, these components align with CWE-613 patterns and Magento's session management architecture.
