Short explanation
The User Frontend plugin up to version 4.3.13 is vulnerable to unauthenticated Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This flaw allows unauthenticated attackers to inject arbitrary web scripts.
This vulnerability requires no authentication, allowing attackers to inject malicious scripts into target pages that execute whenever a user accesses the affected page.
What should be done?
- Follow vendor advisories and updates as the patch status cannot be definitively concluded from reviewed sources
- Temporarily disable guest post submission on frontend forms if applicable
- Review and audit taxonomy field configurations

Show the technical text from the sources
The User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '<taxonomy_field_name> (default: 'category')' parameter in all versions up to, and including, 4.3.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the target installation to have configured a Taxonomy field in text-input mode with guest post submission enabled on at least one frontend form.
