CVE-2026-1674Network attack vector

Contributor-level option modification via missing authorization

Published Mar 4, 2026 · Updated Mar 4, 2026

Missing authorization in Gutena Forms 1.6.0 and earlier allows remote authenticated users to modify WordPress options. The save_gutena_forms_schema() function writes structured array values to WordPress options without checking whether the caller has administrative permission. Contributor access is sufficient to enable disabled settings such as user registration or trigger a site error that denies service.
