The Element Pack Elementor Addons (Header Footer, Template Library, Dynamic Grid & Carousel, Remote Arrows) plugin for WordPress is vulnerable to arbitrary file reads in all versions up to, and including, 5.7.2 via the SVG widget and a lack of sufficient file validation in the render_svg function. This makes it possible for authenticated attackers, with contributor-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
The PHP application receives input from an upstream component, but it does not restrict or incorrectly restricts the input before its usage in "require," "include," or similar functions.
The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.
