调研方向

Reproduce the issue using two incognito windows and the shared game URL, then trace how an unauthenticated visitor is admitted to the guest game and given editor access. Done means the second user is either prevented from joining or remains a spectator with the other player's editor read-only.

描述

bug
Summary

An unauthenticated user can open another guest's Simple Battle by changing the game id in the URL and edit that player's code

Reproduction steps
1. Go to https://codebattle.hexlet.io/ in an incognito window (User A, not logged in)
2. Click "Try simple battle"
3. Copy the game URL (example: https://codebattle.hexlet.io/games/XXXXXX)
4. Open second incognito window (User B, not logged in)
5. Paste the same URL
6. Click at User A editor and type any text
Expected result

User B should be spectator only, or should not join a guest's game at all. The editor must stay read-only

Actual result

User B joins the game as a participant and can change user A code
