Unauthorized game actions via missing CSRF tokens
Published Feb 25, 2026 · Updated Feb 25, 2026
Cross-site request forgery in Talishar before commit 6be3871a14c192d1fb8146cdbc76f29f27c1cf48 allows attackers to perform unauthorized game actions. SubmitChat.php and other state-changing handlers accept requests backed only by victim session state, without unique tokens or Origin/Referer validation. Exploitation requires the gameName and playerID plus interaction with an attacker-controlled website during an active game, and it is limited to actions available to that session.
