Potential fix for https://github.com/microsoft/AcademicContent/security/code-scanning/6
To fix the problem, we should ensure that the value of
voter_idset in the cookie is not directly taken from user input unless it is validated to be safe. The best way to do this is to validate the format ofvoter_idbefore using it, and if it does not meet the expected criteria (e.g., a hex string of a certain length), generate a new random value instead. This prevents attackers from injecting arbitrary values into the cookie. The change should be made in thehellofunction in archive/Events and Hacks/Tech Talks/ContainerDemo/example-voting-app/vote/app.py, specifically around the logic that retrieves and setsvoter_id. No new imports are needed, as the required modules are already present.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
