{"id":"CVE-2026-14488","state":"PUBLISHED","title":"Meta Box AIO <= 3.8.0 - Missing Authorization to Unauthenticated Arbitrary Post Deletion via 'rwmb_frontend_field_object_id' Parameter","description":"The Meta Box AIO plugin for WordPress is vulnerable to Missing Authorization via the template_redirect dispatcher in the MB Frontend Submission extension in versions up to, and including, 3.8.0. This is due to the handle_request() function routing the mbfs_delete action without any capability or ownership check, and the nonce verification in check_ajax() being gated behind is_ajax() which is false for template_redirect requests, making it bypassable. This makes it possible for unauthenticated attackers to delete arbitrary posts and pages by supplying an attacker-controlled post ID via the rwmb_frontend_field_object_id GET parameter on any page that hosts a frontend submission form regardless of whether allow_delete is enabled.","publishedAt":"2026-07-29T09:31:15.974Z","updatedAt":"2026-07-29T14:31:01.547Z","severity":{"score":9.1,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["Meta Box Meta Box AIO"],"affected":[{"vendor":"Meta Box","product":"Meta Box AIO","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.8.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e9506f84-3d33-48e0-8dce-d517e1a923e4?source=cve","https://metabox.io/plugins/meta-box-aio/changelog/"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14488.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14488","state":"PUBLISHED","datePublished":"2026-07-29T09:31:15.974Z","dateUpdated":"2026-07-29T14:31:01.547Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-02T17:05:26.315Z"},"containers":{"cna":{"title":"Meta Box AIO <= 3.8.0 - Missing Authorization to Unauthenticated Arbitrary Post Deletion via 'rwmb_frontend_field_object_id' Parameter","descriptions":[{"lang":"en","value":"The Meta Box AIO plugin for WordPress is vulnerable to Missing Authorization via the template_redirect dispatcher in the MB Frontend Submission extension in versions up to, and including, 3.8.0.
