CVE-2026-93303: HT Contact Form <= 2.10.1 - Unauthenticated Stored DOM-Based Cross-Site Scripting via 'form_data' Rich Text Field via Draft Save/Resume
The HT Contact Form – Drag & Drop Form Builder for WordPress plugin for WordPress is vulnerable to Stored DOM-Based Cross-Site Scripting via 'formdata' 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 draftkey and accesstoken returned directly in the save response.

Frequently Asked Questions
What does an attacker need to exploit this issue?
An attacker does not need authentication, but must obtain the draft_key and access_token returned in the draft-save response. They must then construct a draft resume URL and persuade a user to open it.
Who is exposed to the injected script?
The script executes when a user accesses the attacker-injected page through the crafted draft resume URL. Exposure therefore depends on a user clicking the attacker-supplied resume link.
Are installations using version 2.10.1 affected?
Yes. The issue affects HT Contact Form versions up to and including 2.10.1.
