Summary
Authenticated users can read hidden forum posts through `/forum/get_quotes`
Details

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.
