- CVE-2026-85122, 18 Sep 2026
- The Easy Form Builder by WhiteStudio WordPress plugin before 4.2.0 does not validate a submitted value against the stored configuration for some of its form types, allowing unauthenticated users to store arbitrary content which is then rendered unescaped in an admin page, leading to Stored XSS. CVE record
- CVE-2026-85123, 18 Sep 2026
- The Easy Form Builder by WhiteStudio WordPress plugin before 4.2.0 does not validate a submitted value against the stored configuration for some of its form types, allowing unauthenticated users to create WordPress accounts on a site whose owner has disabled registration. CVE record
- CVE-2026-13439, 21 Jul 2026
- The Easy Form Builder by WhiteStudio plugin for WordPress is vulnerable to Unauthenticated Privilege Escalation to Administrator in versions up to, and including, 4.0.11 This is due to the password recovery flow using the publicly-visible session identifier ('sid') as the password reset token stored in wp_emsfb_temp_links, combined with a publicly-accessible nonce refresh endpoint (Emsfb/v1/nonce/refresh) that issues valid WordPress REST nonces to unauthenticated visitors. This makes it possible for unauthenticated attackers to reset the password of any WordPress user - including administrators - by scraping the public sid from a published login form page, submitting a recovery request for any known user email via Emsfb/v1/forms/message/add, and then calling Emsfb/v1/forms/recovery/efb_set_password with the known sid to set an arbitrary new password and gain full administrator access. CVE record
- CVE-2025-14067, 14 Feb 2026
- The Easy Form Builder plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on multiple AJAX actions in all versions up to, and including, 3.9.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve sensitive form response data, including messages, admin replies, and user information due to a logic error in the authorization check that uses AND (&&) instead of OR (||). CVE record
- CVE-2024-12112, 8 Jan 2025
- The Easy Form Builder - WordPress plugin form builder: contact form, survey form, payment form, and custom form builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name' parameter of the 'add_form_Emsfb' AJAX action in all versions up to, and including, 3.8.8 due to insufficient input sanitization and output escaping and missing authorization checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE record
- CVE-2022-3906, 12 Dec 2022
- The Easy Form Builder WordPress plugin before 3.4.0 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
