# WordPress Fancy Comments plugin: reflected XSS through 1.2.21

The Heateor Support Fancy Comments WordPress plugin does not neutralize input when generating a page, so a crafted link can inject script into the page. An attacker can run JavaScript in a visitor's browser, such as stealing session cookies or acting as the logged-in user.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or in `wp-content/plugins/fancy-facebook-comments/`
- Run `wp plugin get fancy-facebook-comments --field=version` with WP-CLI

## Fix

- Update the Fancy Comments plugin to a version later than `1.2.21`, as the sources do not name a fixed release
- If no fixed version is available, deactivate or remove the plugin
