    How the Exploit Works

    The vulnerability arises from the deserialization of untrusted data. In simpler terms, the affected software improperly transforms data from one format to another (deserialization) and doesn’t adequately verify or sanitize the incoming (untrusted) data. As a result, an attacker can manipulate serialized (formatted) data to inject malicious objects into the application’s memory.

    Conceptual Example Code

    An attacker might exploit the vulnerability with a specially crafted request to a vulnerable endpoint. Below is a conceptual example of how such a request might look like:

    POST /jarvis-theme/endpoint HTTP/1.1
