CVE-2026-84293
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.
What this means for your business
- An attacker can use it remotely, over a network, without a login, and without anyone at your company clicking anything.
- FIRST's prediction model gives it a 0.3% chance of attack attempts being seen in the next 30 days, ranking above 21% of all known flaws.
What to do
- 1Ask your IT team or provider whether any of your systems use the affected product.
- 2If you do, follow the vendor's guidance. No patch reference has been published yet.
