Miggo AIRoot Cause Analysis

The vulnerability stems from cookie decryption combined with unserialization. The EncryptCookies middleware's decryptCookie method called the encrypter with serialization enabled (via static::$serialize=true), making it vulnerable to PHP object injection attacks if the APP_KEY was exposed. The patch in 5.6.30 disabled serialization by default (static::$serialize=false), which addressed the CWE-502 vulnerability by removing unsafe deserialization of client-provided cookies.
