Until a fix is available, users should be cautious about trusting peer values and consider implementing additional authentication checks if possible.
Description
GodotSteam versions 4.17.0 through 4.23.2 contain an authentication bypass vulnerability where the software trusts a peer value of 1 to identify a player as the server. This flaw allows an attacker to forge a grant_gold(1000000) call, potentially granting unauthorized in-game currency.
