To fix the problem, we need to ensure that the user input does not directly influence the URL in a way that could lead to SSRF. One effective way to do this is to use a whitelist of allowed IDs or to ensure that the constructed URL is safe. Since the IDs are already validated to be 32-character hexadecimal strings, we can focus on ensuring the base URL and query parameters are safe.
- Use a fixed base URL from an environment variable.
- Ensure the IDs are appended in a controlled manner.
- Validate the final URL before making the request.

To fix the problem, we need to ensure that the itemId parameter from context.query is validated against a known set of valid item IDs or a specific pattern before constructing the itemUrl. This will prevent attackers from manipulating the itemId to create malicious URLs.
The best way to fix this is to implement a validation function that checks if the itemId is in a valid format (e.g., a numeric ID or a specific pattern) and only then constructs the itemUrl. If the itemId is not valid, we should return a notFound response.

To fix the problem, we need to ensure that all occurrences of the specified characters are removed from the user input. This can be achieved by using a regular expression with the global flag (g). Additionally, we should ensure that the backslash character itself is also escaped properly.
The best way to fix this is to replace the current replace method call with a regular expression that matches all occurrences of the specified characters and removes them. This change should be made on line 107.
