Multiple cross-site scripting (XSS) vulnerabilities in the VideoWhisper Video Presentation plugin before 3.31 for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) room_name parameter to c_login.php or (2) room parameter to index.php in vp/.

The videowhisper-video-presentation plugin 3.31.17 for WordPress allows remote attackers to execute arbitrary code because vp/vw_upload.php considers a file safe when "html" are the last four characters, as demonstrated by a .phtml file containing PHP code.
