Description

The WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, & More plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the start_timestamp parameter in all versions up to, and including, 1.9.5 due to insufficient input sanitization and output escaping.
