Mitigation checklist

Recommended fix / mitigation

To mitigate this issue, ensure that all applications persisting `URLField` data into the Django database perform proper model validation. This is especially critical for data imported via direct queryset writes, deserialization, or bulk import processes, which may bypass standard `ModelForm` or admin validation. Implementing robust input validation at the application level for all `URLField` inputs will prevent the storage of malicious URLs.
