Is this vulnerability remotely exploitable over the internet?

Yes, if the Docker API /crawl endpoint is exposed to the internet or a wide internal network without strong access controls, an attacker can exploit it remotely by sending crafted HTTP requests containing malicious hooks payloads.

Does an attacker need valid credentials or prior access to exploit this?

No, the described issue allows unauthenticated exploitation when the endpoint is reachable. The main requirement is network access to the affected /crawl API, not prior login or account presence.

What is the safest general fix pattern for this kind of issue?

The most robust fix is to completely remove execution of user-supplied code. Replace raw hooks with a safe, predefined set of behaviors or callbacks controlled by the server, and avoid exec()/eval() on any data influenced by clients. If extensibility is required, use a vetted plugin system or configuration-driven logic rather than direct code injection.
