CVE-2026-5112

/// Technical description

The Gravity Forms plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in versions up to and including 2.10.0. This is due to insufficient input validation and output escaping of Calculation Product field product names when rendered inside Repeater fields. The validate() method in the GF_Field_Calculation class only validates the quantity field (.3) and completely ignores the product name field (.1), allowing malicious HTML to pass through validation.

Subsequently, when an entry is viewed in wp-admin, the get_value_entry_detail() method concatenates the unescaped product name directly into the output string, which is then rendered by the repeater's get_value_entry_detail() method without further escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts via form submissions that will
