Technical details
The plugin fails to properly neutralize user input during web page generation, allowing stored XSS attacks. Successful exploitation requires a privileged user account (contributor level or above) to perform an action such as submitting a form or crafting a page. An attacker with the necessary privileges can inject malicious JavaScript that persists in the database and executes when other users view the affected content.
