To fix the SSRF vulnerability, we need to validate the user-provided input before incorporating it into the URL. One approach is to maintain a list of authorized URLs or URL prefixes and ensure that the constructed URL matches one of these authorized patterns. Alternatively, we can restrict the URL construction to a specific host or URL prefix.
In this case, we will implement a validation method that checks if the constructed URL starts with a predefined URL prefix. This ensures that the URL is within the expected domain and prevents SSRF attacks.

Refactor the implementation using java.net with OkHttp.
