Camaleon CMS versions 2.7.5 through 2.9.1 fail to validate redirect targets when fetching remote files in the Upload from URL media feature. Authenticated attackers can supply URLs that pass initial validation but redirect to internal network addresses, allowing server-side request forgery to internal services.
