10 CVE

  1. CVE-2026-82220 5.3 Moyenne

    WPMU DEV Forminator

    Unauthenticated Other Vulnerability Type in Forminator <= 1.57.1 versions.

  2. CVE-2026-18324 7.2 Élevée

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Rich-Text Textarea Field in all versions up to, and including, 1.57.0.1 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 that the targeted Textarea field has the Rich-Text editor option enabled.

  3. CVE-2026-18328 7.2 Élevée

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to DOM-Based Reflected Cross-Site Scripting via the 'error_description' parameter in all versions up to, and including, 1.57.0 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. The vulnerability is only triggerable on pages hosting a Forminator form configured to use the Stripe Checkout Sessions payment API, which became the default in 1.56.0.

  4. CVE-2026-18323 7.2 Élevée

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Radio Field (Save and Continue Draft) in all versions up to, and including, 1.57.0.2 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. This is exploitable because the Save-and-Continue draft submission AJAX endpoint is registered as nopriv, allowing unauthenticated attackers to bypass radio field option-membership validation and persist a crafted payload that, when rendered on the Submissions admin page, is auto-executed via the bundled Inputmask library's data-attribute callback binding.

  5. CVE-2026-66583 9.8 Critique

    WPMU DEV Forminator

    Unauthenticated PHP Object Injection in Forminator <= 1.57.0 versions.

  6. CVE-2026-15748 9.8 Critique

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.56.1 via the handle_file_upload function. This is due to insufficient file type validation in handle_file_upload, where the dangerous-extension blocklist performs exact-key matching that is bypassed by pipe-alternative MIME type keys, combined with a public submission handler that trusts attacker-controlled upload field configuration injected via a forged Select field value. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

  7. CVE-2026-12998 5.3 Moyenne

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.55.0.2 via the 'draft' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to enumerate sequential integer entry IDs via the 'draft' parameter and read other users' saved draft form data, including names, email addresses, phone numbers, addresses, and free-form message content. This is only exploitable on forms that have the 'Save and Continue' feature enabled.

  8. CVE-2026-28143 7.1 Élevée

    WPMU DEV Forminator

    Unauthenticated Cross Site Scripting (XSS) in Forminator <= 1.56.0 versions.

  9. CVE-2026-28111 8.8 Élevée

    WPMU DEV Forminator

    Contributor Privilege Escalation in Forminator <= 1.56.0 versions.

  10. CVE-2026-18325 7.2 Élevée

    wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder

    The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Forged Upload Record via Select Field in all versions up to, and including, 1.56.1 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. The exploit is possible because Forminator_Core::sanitize_array() skips all filtering for keys prefixed with 'select-', and set_field_data() treats a submitted 'return' member as a trusted internal flag — allowing an unauthenticated attacker to forge and persist a complete upload field record with an arbitrary file_url value without any sanitization or validation.
