Arbitrary file upload in Kali Forms — Contact Form & Drag-And-Drop Builder
CVE-2026-11579
The Kali Forms — Contact Form & Drag-and-Drop Builder WordPress plugin before 2.4.17 does not verify that a file upload is made against an existing form configured with a file-upload field, accepting uploads regardless of whether any such form exists, which allows unauthenticated users to upload files to the WordPress Media Library; the uploads are limited to WordPress's default-allowed MIME types, so this does not lead to code execution.
