## What is CVE-2026-11579?

CVE-2026-11579 is a medium-severity vulnerability in Unknown Kali Forms — Contact Form & Drag-and-Drop Builder, published on 15 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-434 (Unrestricted Upload of File with Dangerous Type)
