Description
The Webcam Microphone Screen Recorder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'exiturl' attribute of the videowhisper_html5recorder shortcode in versions 3.1 through 3.3.1. This is due to insufficient output escaping: the value is only passed through sanitize_url(), which keeps single quotes, and is then placed directly inside a single-quoted JavaScript string in an inline script. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages that will execute whenever a user who is permitted to load the recorder (by default, any logged-in user) accesses an injected page.
