Unauthenticated File Upload in Kali Forms WordPress Plugin

Publication date: 2026-07-15

Last updated on: 2026-07-15

Assigner: WPScan

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.

Executive Summary

CVE-2026-11579 is a vulnerability in the Kali Forms WordPress plugin before version 2.4.17. It allows unauthenticated users to upload files to the WordPress Media Library without needing a valid form with a file-upload field. The plugin does not check if an upload request matches an existing form.

Detection Guidance

Check if the Kali Forms plugin version is below 2.4.17. Use WordPress admin panel or run: wp plugin list | grep kali-forms. Inspect server logs for unauthorized file uploads or unusual Media Library activity.

Impact Analysis

This vulnerability could allow attackers to upload files to your WordPress site, potentially consuming storage space or exposing sensitive data. Files are temporarily stored and publicly accessible for about 15 minutes before automatic deletion. While code execution is prevented due to MIME type restrictions, unauthorized uploads may still disrupt operations or violate privacy.

Compliance Impact

This vulnerability may pose compliance risks by allowing unauthorized file uploads to your WordPress Media Library. Temporary public access to files could violate data protection policies like GDPR or HIPAA if sensitive or personal data is involved. Organizations must ensure proper controls to prevent unauthorized uploads and data exposure.

Mitigation Strategies

Update Kali Forms plugin to version 2.4.17 or later immediately. If updating is not possible, disable the plugin temporarily until an update is applied. Review Media Library for unauthorized files and remove any suspicious uploads.
