October CMS: Incomplete Scheme Validation in Image Resizer

The image resizer classified external sources by testing whether the source string began with the substring http, and the string-source branch in ResizeImageItem::fromObject accepted any value containing :// as a URL. As a result, non-https PHP stream wrappers such as phar://, file:// and ftp://...
