What is CVE-2026-123017?

The GodotSteam framework versions 4.17 through 4.23.2 are vulnerable to an improper peer validation issue. Specifically, the system incorrectly trusts a peer value of 1 to denote that a player is acting as the server. This exploitation allows malicious users to forge calls such as grant_gold(1000000), enabling them to manipulate game resources unjustly. The implications can severely impact game integrity and fair play, making it essential for developers and users to address this vulnerability promptly. Immediate updates and patches are recommended to mitigate the associated risks.

Affected Version(s)

GodotSteam 4.17.0 <= 4.23.2
