Overview

CVE-2026-12418 is a medium-severity vulnerability. It was published on July 9, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
