Gutenberg Blocks with AI by Kadence WP <= 3.6.1 - Missing Authorization to Authenticated (Contributor+) Unauthorized Media Upload

Missing Authorization
CVE CVE-2026-2633
CVSS Medium (4.3)
Publicly Published February 17, 2026

Researcher Ali Sünbül
Description

The Gutenberg Blocks with AI by Kadence WP plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.6.1. This is due to a missing capability check in the `process_image_data_ajax_callback()` function which handles the `kadence_import_process_image_data` AJAX action. The function's authorization check via `verify_ajax_call()` only validates `edit_posts` capability but fails to check for the `upload_files` capability. This makes it possible for authenticated attackers, with Contributor-level access and above, to upload arbitrary images from remote URLs to the WordPress Media Library, bypassing the standard WordPress capability restriction that prevents Contributors from uploading files.
