MyBB (aka MyBulletinBoard) 1.4.3 includes the sensitive my_post_key parameter in URLs to moderation.php with the (1) mergeposts, (2) split, and (3) deleteposts actions, which allows remote attackers to steal the token and bypass the cross-site request forgery (CSRF) protection mechanism to hijack the authentication of moderators by reading the token from the HTTP Referer header.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
