What the vulnerability does
01Description
The Payment Forms for Paystack plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes like 'datepicker', 'textarea', and 'text' in all versions up to, and including, 4.0.2 due to insufficient input sanitization and output escaping on user supplied attributes.
