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.","severity":{"version":"3.1","score":4.3,"vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-12","score":0.00369,"percentile":0.31156,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-862"],"published":"2026-02-18T06:42:42Z","modified":"2026-06-17T10:31:26Z","products":[{"vendor":"stellarwp","product":"kadence blocks — page builder toolkit for gutenberg editor"}],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9c06e0a9-a13a-4cee-a1a5-c43c114b2dbf?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.5.32/includes/class-kadence-blocks-prebuilt-library.php#L789"},{"url":"https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.5.32/includes/class-kadence-blocks-prebuilt-library.php#L1177"},{"url":"https://plugins.trac.wordpress.org/changeset?sfp_email=\u0026sfph_mail=\u0026reponame=\u0026new=3454881%40kadence-blocks%2Ftrunk\u0026old=3453204%40kadence-blocks%2Ftrunk\u0026sfp_email=\u0026sfph_mail="},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2633"},{"url":"https://github.com/advisories/GHSA-gch6-cfhh-c44p"}],"sources":{"cve":[{"id":"CVE-2026-2633","title":"Gutenberg Blocks with AI by Kadence WP \u003c= 3.6.1 - Missing Authorization to Authenticated (Contributor+) Unauthorized Media Upload","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.
