The Happy Addons plugin, which is used with WordPress, has a security issue called Stored Cross-Site Scripting. This means that the plugin does not properly clean up user input and output, making it possible for hackers to insert harmful code into pages. This can affect users who have contributor-level access or higher, and the harmful code will execute whenever a user opens the affected page.
