What is CVE-2026-93303?
CVE-2026-93303 is a high-severity cross-site scripting vulnerability in htplugins HT Contact Form – Drag & Drop Form Builder for WordPress, published on 25 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The HT Contact Form – Drag & Drop Form Builder for WordPress plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via 'form_data' Rich Text Field via Draft Save/Resume in all versions up to, and including, 2.10.1 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 tricking a user into clicking an attacker-supplied draft resume URL, which the attacker constructs using the draft_key and access_token returned directly in the save response.
