A file upload functionality in Piranha CMS 11.1 allows authenticated remote attackers to upload a crafted PDF file to /manager/media.

In PiranhaCMS, versions 4.0.0-alpha1 to 9.2.0 are vulnerable to cross-site request forgery (CSRF) when performing various actions supported by the management system, such as deleting a user, deleting a role, editing a post, deleting a media folder etc., when an ID is known.
