Responsibility for hacking an onion resource?

Question

Tor

Naive question, but still.
As I understand it, there is no legal regulation in the Tor network.
But does this guarantee complete anarchy?
Let's say there is some onion resource. When studying it, vulnerabilities were identified, access was gained to the tor-hidden-server on the user's local machine. Can the provider of the explorer and the owner of the local machine with the onion resource try to prosecute the breach in such a situation?
