CVE-2026-84293: Repeater Fields for Gravity Forms <= 3.0.4 - Unauthenticated Stored Cross-Site Scripting via Repeated Multi-Input Sub-Field Values
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 eschtml() at the output stage in version 3.0.4.

Frequently Asked Questions
Which form configurations are affected?
The issue affects repeater fields containing multi-input sub-field types, including Name, Address, and Checkbox fields. Scalar single-input values are escaped with esc_html() at output in version 3.0.4 and are not affected by this specific issue.
Does exploitation require an account or user interaction?
No attacker account or user interaction is required to submit the malicious value. The injected script executes later when a user accesses a page where the stored value is rendered.
Who is exposed to script execution?
Users who access a page containing an attacker-injected repeated multi-input sub-field value may execute the stored script in their browser. The vulnerability can affect confidentiality and integrity in the context of the viewing user's session.
