CVE-2026-5111Public exploitNetwork attack vector

Unauthenticated stored XSS via Hidden Product name

Published May 2, 2026 · Updated May 2, 2026

Stored XSS in Gravity Forms 2.10.0 and earlier allows remote attackers to inject scripts through Hidden Product fields in Repeater forms. Repeater subfields bypass state validation, while the Hidden Product validate() method ignores the product name that get_value_entry_detail() outputs without escaping. Exploitation requires a public form containing this nested field configuration and an administrator to view the stored entry detail, enabling script execution in that browser context.
