Description
Camaleon CMS before 2.9.2 contains a missing authorization vulnerability in Admin::MediaController that allows low-privileged authenticated users to bypass the role-based Media permission. Attackers can POST to /admin/media/upload to store files, read private media via download_private_file, and use crop with saved_avatar to change other users' avatars.
