XSS in Wedevs User Frontend – Membership, Registration, Profile, Directory & Content Restriction With Post Submission

CVE-2026-109214

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.
