# CVE-2026-45697

> 9.8 CRITICAL · 🧪 PoC

## Beschreibung

Formie is a Craft CMS plugin for creating forms. Prior to 2.2.20 and 3.1.24, unauthenticated users could submit crafted values into Hidden fields (with Default value → Custom) that were evaluated as Twig during submission handling, which could lead to serious compromise of the Craft site (depending on template/sandbox behavior). This vulnerability is fixed in 2.2.20 and 3.1.24.
