The Plus Addons for Elementor plugin for WordPress is vulnerable to arbitrary file reads in versions up to, and including 4.1.9 (pro) and 2.0.6 (free). The plugin has a feature to add an "Info Box" to an Elementor created page. This Info Box can include an SVG image for the box. Unfortunately, the plugin used file_get_contents with no verification that the file being supplied was an SVG file, so any user with access to the Elementor page builder, such as contributors, could read arbitrary files on the WordPress installation.

The Plus Addons for Elementor plugin for WordPress is vulnerable to privilege escalation in versions up to, and including 4.1.9 (pro) and 2.0.6 (free). The plugin adds a registration form to the Elementor page builders functionality. As part of the registration form, users can choose which role to set as the default for users upon registration. This field is not hidden for lower-level users so any user with access to the Elementor page builder, such as contributors, can set the default role to administrator. Since contributors can not publish posts, only author+ users can elevate privileges without interaction via a site administrator (to approve a post).
