Summary
Formie: Pre-authenticated server-side template injection in Hidden fields
Details

Impact

  • 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).
  • Sites with public Formie forms that include at least one Hidden field with that configuration.
  • No CP login for the reported chain.

Patches

Workarounds

  • Temporarily remove Hidden fields from public forms or switch Hidden default away from Custom where feasible
  • Otherwise, upgrade to patched versions
