How broadly exploitable is this SSRF vulnerability?

Exploitability depends on how exposed the `open-url` endpoint is and what the server can reach on the network. In environments where the endpoint is accessible to untrusted users and the server has access to internal or cloud management networks, the practical risk is significant.

What level of access does an attacker need to exploit this issue?

The attacker needs the ability to send HTTP requests to the vulnerable `open-url` API endpoint and control the `url` parameter. This might require an authenticated account, a tenant in a shared environment, or just network access if the endpoint is publicly reachable.

What is the safest general fix pattern?

The safest pattern is to avoid making arbitrary outbound requests based on user input. If the feature is required, enforce strict allowlisting of destinations or URL templates, block internal address ranges, and validate schemes to limit the reachable surface.
