Technical details

The leaderboard page fails to properly neutralize user names during rendering, allowing stored XSS injection. An authenticated attacker with the ability to modify their user name can craft a payload that executes arbitrary JavaScript when other users view the leaderboard page. This requires user interaction (viewing the leaderboard) and authenticated access to set the malicious name.
