The User Notes add-on for WordPress has a security flaw that allows for Stored Cross-Site Scripting. This means that hackers with administrator-level access or higher can insert harmful code into web pages that will run when a user visits the page. This only impacts multi-site setups and installations where the option to filter HTML has been turned off.
