Stored XSS in Repeater Fields for Gravity Forms WordPress Plugin

Publication date: 2026-09-09

Last updated on: 2026-09-09

Assigner: Wordfence

Description

The Repeater Fields for Gravity Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Repeated Multi-Input Sub-Field Values in all versions up to, and including, 3.0.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability only affects multi-input sub-field types within a repeater (such as Name, Address, and Checkbox fields), as scalar single-input field values are escaped with esc_html() at the output stage in version 3.0.4.
