{"cve":"CVE-2026-12418","nvd":{"published":"2026-07-09T08:16:46.000","modified":"2026-07-09T16:20:12.533","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-639"],"references":["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/browser/wp-user-frontend/tags/4.3.1/includes/Traits/FieldableTrait.php#L478","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.6/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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-12418","score":0.00423,"percentile":0.36614,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
