CVE-2024-23522Network attack vector

Unauthenticated admin-page defacement via unsanitized form fields

Published May 17, 2024 · Updated Apr 28, 2026

HTML injection in Strategy11 LLC Formidable Forms 6.7 and earlier allows remote attackers to inject arbitrary HTML through form fields. Submitted field values are stored without sufficient neutralization and later rendered as HTML on the administrator Entries View page. No authentication is required to submit the content, but an administrator must view the stored entry; impact is bounded to admin-page defacement or redirection.
