DescriptionCVE.org

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.

AnalysisAI

Stored Cross-Site Scripting in the Forminator Forms WordPress plugin (all versions through 1.57.0.1) enables unauthenticated attackers to inject persistent malicious scripts via Rich-Text Textarea fields, which execute in any visitor's or administrator's browser upon page access. The flaw originates from insufficient input sanitization at submission time and missing output escaping at render time, with vulnerable code paths confirmed across multiple plugin files including textarea.php, abstract-class-front-action.php, and admin-page-entries.php. …
