Input validation vulnerability in muse.ai video embedding 0.4

The video embedding plugin for WordPress called muse.ai can be hacked through a technique called Stored Cross-Site Scripting. This is because the plugin does not properly check and clean up any information that users enter, making it easy for malicious hackers to inject their own code into web pages. This can only be done by those who are logged into the website with contributor-level access or higher. Once the code is injected, it will run whenever a user visits that page.
