The register_routes function in wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php in the REST API in WordPress 4.7.x before 4.7.2 does not require an integer identifier, which allows remote attackers to modify arbitrary pages via a request for wp-json/wp/v2/posts followed by a numeric value and a non-numeric value, as demonstrated by the wp-json/wp/v2/posts/123?id=123helloworld URI.
In WordPress before 4.7.3, there is authenticated Cross-Site Scripting (XSS) via Media File Metadata. This is demonstrated by both (1) mishandling of the playlist shortcode in the wp_playlist_shortcode function in wp-includes/media.php and (2) mishandling of meta information in the renderTracks function in wp-includes/js/mediaelement/wp-playlist.js.
In WordPress before 4.7.3, there is cross-site request forgery (CSRF) in Press This (wp-admin/includes/class-wp-press-this.php), leading to excessive use of server resources. The CSRF can trigger an outbound HTTP request for a large file that is then parsed by Press This.
Cross-site scripting (XSS) vulnerability in platinum_seo_pack.php in the Platinum SEO plugin before 1.3.8 for WordPress allows remote attackers to inject arbitrary web script or HTML via the s parameter.
Cross-site scripting (XSS) vulnerability in login-with-ajax.php in the Login With Ajax (aka login-with-ajax) plugin before 3.0.4.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the callback parameter in a lostpassword action to wp-login.php.
Cross-site scripting (XSS) vulnerability in the userphoto_options_page function in user-photo.php in the User Photo plugin before 0.9.5.2 for WordPress allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to wp-admin/options-general.php. NOTE: some of these details are obtained from third party information.
