Multi Step Form <= 1.2.5 - Stored Cross-Site Scripting

The Mondula Multi Step Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘fw_wizard_save’ action in versions up to, and including, 1.2.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The following parameters are affected: data[wizard][steps][0][title] data[wizard][steps][0][headline] data[wizard][steps][0][copy_text] data[wizard][steps][0][parts][0][title] data[wizard][steps][0][parts][0][blocks][0][label] data[wizard][steps][0][parts][0][blocks][0][format] data[wizard][steps][0][parts][0][blocks][1][label] data[wizard][steps][0][parts][0][blocks][2][label] data[wizard][steps][0][parts][0][blocks][3][label] data[wizard][settings][thankyou].
