HIGH CVE-2026-18323 Deferred

Forminator draft submissions permit unauthenticated stored cross-site scripting

Forminator through 1.57.0.2 exposes its Save-and-Continue draft submission AJAX path to unauthenticated users. An attacker can bypass radio-field option membership validation and persist a crafted value; the bundled Inputmask library binds the stored data attribute as a callback when an administrator opens the submission in the Submissions screen, executing script in that privileged session.

What to do

Update, patch or deactivate.

Version 1.57.1 is available, but its official changelog does not clearly identify this CVE. Update to the latest release, inspect saved draft submissions for unexpected radio-field data, and invalidate administrator sessions if malicious entries were viewed. The official upstream changelog lists version 1.57.1, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

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.
