Description

The Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 2.10.0. This is due to insufficient input validation and output escaping on Hidden Product field values when used inside Repeater fields, where repeater subfields bypass state validation checks and the Hidden Product validate() method only validates the quantity field while ignoring the product name field that is later output without proper escaping in the get_value_entry_detail() method. This makes it possible for unauthenticated attackers to inject arbitrary web scripts through form submissions that will execute whenever an administrator views the entry details.

Affected products

• Gravity Forms: through 2.10.0
