"CVE-2026-45697"
],
"details": "### Impact\n- 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).\n- Sites with public Formie forms that include at least one Hidden field with that configuration.\n- No CP login for the reported chain.\n\n### Patches\n- [2.2.20](https://github.com/verbb/formie/releases/tag/2.2.20), [3.1.24](https://github.com/verbb/formie/releases/tag/3.1.24)\n\n### Workarounds\n- Temporarily remove Hidden fields from public forms or switch Hidden default away from Custom where feasible\n- Otherwise, upgrade to patched versions",
