To fix the problem, we need to ensure that the hostname check is robust and cannot be bypassed by embedding the allowed host in an unexpected location. We will use urlparse to parse the URL and then check the hostname to ensure it matches the allowed host correctly.
- Parse the URL using
urlparse. - Check if the hostname ends with the allowed host and ensure it is a valid subdomain by checking the preceding character.
- Update the
_put_presigned_urlmethod to implement this check.

Potential fix for https://github.com/raga-ai-hub/RagaAI-Catalyst/security/code-scanning/5
To fix the problem, we need to ensure that the URL is properly parsed and validated. Instead of checking for the substring "blob.core.windows.net" within the URL, we should parse the URL and check the hostname specifically. This will prevent malicious URLs from bypassing the check by embedding the allowed host in an unexpected location.
The best way to fix this is to use the
urlparsefunction from theurllib.parsemodule to parse the URL and then check the hostname. We will update the_put_presigned_urlmethod to implement this change.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
