This results from an incomplete patch for CVE-2018-12426. Arbitrary file upload is achieved by using a non-blacklisted executable file extension in conjunction with a whitelisted file extension, and prepending \"magic bytes\" to the payload to pass MIME checks. Specifically, an unauthenticated remote user submits a crafted file upload POST request to the REST api remote_upload endpoint. The file contains data that will fool the plugin's MIME check into classifying it as an image (which is a whitelisted file extension) and finally a trailing .phtml file extension."}, {"lang": "es", "value": "El plugin WP Live Chat Support Pro a trav\u00e9s de 8.0.26 para WordPress contiene una vulnerabilidad de carga de archivos arbitraria.
