The Divi Plus plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 2.4.0 via the 'svg_image' parameter of the /wp-json/elicus/v1/dipl-modules/svg-animator REST endpoint. This is due to the endpoint's permission callback (SVGAnimatorController::index_permission) returning true unconditionally combined with insufficient validation of the 'svg_image' input — sanitize_text_field() and esc_html() do not restrict filesystem paths, the file:// stream wrapper, or arbitrary URLs — before it is passed to file_get_contents() (with a wp_remote_get() fallback) and the raw response body is returned in the JSON 'html' field. This makes it possible for unauthenticated attackers to read arbitrary files on the affected site's server which may make remote code execution possible.
