Is this vulnerability remotely exploitable?

Yes. As described, the attack can be carried out remotely if an attacker can reach the WebUploader `preview.php` endpoint over the network and send crafted data.

What level of access does an attacker need?

Typically only network access to the affected tpadmin instance is required. If the endpoint is publicly exposed and does not enforce authentication or strong access control, any external user may attempt exploitation.

What is the safest general fix pattern?

The safest pattern is to remove unsafe deserialization entirely from the upload/preview path, replacing it with explicit, typed parsing of simple formats and validating all incoming data against strict expectations before processing.
