PDF for WPForms Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the PDF for WPForms + Drag and Drop Template Builder plugin for WordPress, affecting all versions through 4.6.0. The vulnerability arises from inadequate input sanitization and output escaping on user-supplied attributes, particularly within the yeepdf_dotab shortcode. This flaw allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected pages.

Impact

Remediation

Users are advised to update the PDF for WPForms + Drag and Drop Template Builder plugin to version 4.8.0 or a newer patched version.
