Can you explain this vulnerability to me?
The MetForm Pro plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its Quiz feature in all versions up to and including 3.9.6.

These injected scripts are stored and then executed whenever a user accesses the affected page, potentially compromising the user's browser.
