Summary
The User Frontend plugin for WordPress by wedevs is affected up to and including 4.3.13. Insufficient input sanitization and output escaping of a taxonomy field parameter lets injected content persist on the site (CWE-79). An unauthenticated attacker can inject arbitrary web scripts that run whenever a user accesses the injected page. Exploitation requires a taxonomy field configured in text-input mode with guest post submission enabled on at least one frontend form.
