Description
The Broadcast Live Video – Live Streaming : WebRTC, HLS, RTSP, RTMP plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'id' parameter of the vwls_channels AJAX action in all versions up to, and including, 7.3.14, due to insufficient input sanitization and output escaping. The value is sanitized only with sanitize_text_field() and is echoed into JavaScript variable names in an inline script and in inline event handlers. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
