Miggo AIRoot Cause Analysis

The vulnerability stemmed from session handlers not including the session cookie name in storage keys. The commit adds sessionCookieName as a prefix to session IDs in database queries (DatabaseHandler) and key prefixes (Memcached/Redis). The original vulnerable functions handled session data without this namespacing, allowing session ID collisions between different cookies. The high confidence comes from direct correlation between the patch changes and the vulnerability description, with explicit modifications to these functions in the provided diffs.
