CVE-2026-33398

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.

Summary		(es) NamelessMC es un software de sitio web para servidores de Minecraft. En la versión 2.2.4, modules/Forum/pages/forum/get_quotes.php solo verifica si el llamador ha iniciado sesión, luego lee una publicación mediante un ID de 'post' controlado por el atacante y devuelve su contenido. El ayudante de backend en modules/Forum/classes/Forum.php no aplica las ACL de foro o tema. En contraste, la página de tema normal en modules/Forum/pages/forum/view_topic.php aplica la visibilidad del foro y 'view_other_topics'.
