The actions defined inside of the MediaController class do not check whether a given path is inside a certain path (e.g. inside the media folder). If an attacker performed an account takeover of an administrator account (See: GHSL-2024-184) they could delete arbitrary files or folders on the server hosting Camaleon CMS. The crop_url action might make arbitrary file writes (similar impact to GHSL-2024-182) for any authenticated user possible, but it …
