Description

NamelessMC is website software for Minecraft servers. In version 2.2.4, `modules/Forum/pages/forum/get_quotes.php` only checks whether the caller is logged in, then reads a post by attacker-controlled `post` ID and returns its content. The backend helper in `modules/Forum/classes/Forum.php` does not enforce forum or topic ACLs. In contrast, the normal topic page in `modules/Forum/pages/forum/view_topic.php` enforces forum visibility and `view_other_topics`. Any low-privileged authenticated user can enumerate post IDs and read content from hidden, private, or staff-only forums. Version 2.2.5 fixes the issue.
