CVE-2026-86194Network attack vector

Restricted form-action execution via unchecked cross-page lookup

Published Sep 5, 2026 · Updated Sep 5, 2026

Improper authorization in GetGrav Grav Form Plugin before 9.1.22 allows remote attackers to execute restricted form actions. When getForm() searches other pages by a posted form name, it selects the first match without checking whether the source page is published or accessible. Anonymous access to any public page is sufficient to trigger configured save, upload, email, or call actions on a protected form.
