Doc Text:
A vulnerability was identified in Plack::Middleware::Session::Cookie when session data is deserialized from cookies using Storable::thaw. If the secret parameter is not configured or is compromised, an attacker can craft a malicious session cookie containing serialized objects. Because Storable::thaw processes untrusted data without restrictions, this may lead to execution of arbitrary code during object deserialization.
