Bludit CMS through 3.22.0 contains a mass assignment vulnerability that allows authenticated users with the Author role to modify privileged page fields reserved for administrators by injecting reserved parameters into a content save request. Attackers can submit reserved fields such as type and username through the Pages::edit() function in bl-kernel/pages.class.php, which iterates all fields declared in dbFields without per-field authorization, enabling an Author to convert pages to static site-wide navigation entries or transfer page ownership to arbitrary accounts.
