{"id":"CVE-2026-2633","state":"PUBLISHED","title":"Gutenberg Blocks with AI by Kadence WP <= 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. 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.","publishedAt":"2026-02-18T06:42:42.888Z","updatedAt":"2026-04-08T17:11:22.271Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["stellarwp Kadence Blocks — Page Builder Toolkit for Gutenberg Editor"],"affected":[{"vendor":"stellarwp","product":"Kadence Blocks — Page Builder Toolkit for Gutenberg Editor","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.6.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9c06e0a9-a13a-4cee-a1a5-c43c114b2dbf?source=cve","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.5.32/includes/class-kadence-blocks-prebuilt-library.php#L789","https://plugins.trac.wordpress.org/browser/kadence-blocks/tags/3.5.32/includes/class-kadence-blocks-prebuilt-library.php#L1177","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3454881%40kadence-blocks%2Ftrunk&old=3453204%40kadence-blocks%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2633.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2633","state":"PUBLISHED","datePublished":"2026-02-18T06:42:42.888Z","dateUpdated":"2026-04-08T17:11:22.271Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-17T17:42:46.510Z"},"containers":{"cna":{"title":"Gutenberg Blocks with AI by Kadence WP <= 3.6.1 - Missing Authorization to Authenticated (Contributor+) Unauthorized Media Upload","descriptions":[{"lang":"en","value":"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.
