[fazledyn-or]

Details

While triaging your project, our bug fixing tool generated the following message(s)-

In file: ProfileMiddleware.py, there is a method that creates a temporary file using an unsafe API mktemp. The use of this method is discouraged in the Python documentation. iCR suggested that a temporary file should be created using mkstemp which is a safe API. iCR replaced the usage of mktemp with mkstemp.
