# ThemeHunk Customizer WordPress plugin: reflected XSS through 2.8.7

ThemeHunk Customizer, a WordPress plugin, does not neutralize input in generated pages, enabling reflected cross-site scripting. An attacker who gets a victim to open a crafted link can run script in the victim's browser session on the affected site.

_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 with `wp plugin get themehunk-customizer --field=version`
- Compare against the fixed release named in the advisory; the sources do not give a fixed version

## Fix

- Update ThemeHunk Customizer (`themehunk-customizer`) to a version later than `2.8.7`; the sources do not name the exact fixed release
- If no fixed version exists, deactivate and remove the plugin
