{"id":"CVE-2026-12418","state":"PUBLISHED","title":"User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration <= 4.3.7 - Insecure Direct Object Reference to Unauthenticated Arbitrary Post Modification via 'wpuf_files_data' Parameter","description":"The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.7 via the 'wpuf_files_data' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite the post_title, post_content, and post_excerpt of any arbitrary post on the site, including posts authored by administrators. Exploitation requires access to any WPUF post submission form; this is achievable by users with no WordPress role, as the wpuf_submit_post AJAX action is gated only by a nonce with no capability check for the downstream post-edit operation.","publishedAt":"2026-07-09T07:55:13.665Z","updatedAt":"2026-07-09T14:39:37.233Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wedevs User Frontend: AI Powered Frontend Posting, User Directory, Profile Builder, Membership & User Registration"],"affected":[{"vendor":"wedevs","product":"User Frontend: AI Powered Frontend Posting, User Directory, Profile Builder, Membership & User Registration","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.3.7","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8f66e25f-b67e-4227-95fe-69b40551af61?source=cve","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.6/includes/Traits/FieldableTrait.php#L478","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.6/includes/Ajax/Frontend_Form_Ajax.php#L35","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.6/includes/Traits/FieldableTrait.php#L468","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.1/includes/Traits/FieldableTrait.php#L478","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.1/includes/Ajax/Frontend_Form_Ajax.php#L35","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.1/includes/Traits/FieldableTrait.php#L468","https://plugins.trac.wordpress.org/changeset?reponame=&old=3578622%40wp-user-frontend&new=3578622%40wp-user-frontend"],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12418.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12418","state":"PUBLISHED","datePublished":"2026-07-09T07:55:13.665Z","dateUpdated":"2026-07-09T14:39:37.233Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-16T16:03:46.619Z"},"containers":{"cna":{"title":"User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration <= 4.3.7 - Insecure Direct Object Reference to Unauthenticated Arbitrary Post Modification via 'wpuf_files_data' Parameter","descriptions":[{"lang":"en","value":"The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.7 via the 'wpuf_files_data' parameter due to missing validation on a user controlled key.
