Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The User Frontend: AI Powered Frontend Posting, User Directory, Profile, Membership & User Registration plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the draft_post() function in all versions up to, and including, 4.2.8. This makes it possible for unauthenticated attackers to modify arbitrary posts (e.g. unpublish published posts and overwrite the contents) via the 'post_id' parameter.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The User Frontend WordPress plugin has a broken access control vulnerability in the draft_post() function, which lacks proper capability checks. This allows unauthenticated attackers to modify arbitrary posts by supplying a post_id parameter, enabling unpublishing of posts or content overwrite.

MitigationUpdate the plugin to a version beyond 4.2.8 once a patch is released. Until then, consider disabling the plugin or implementing WAF rules to block requests to the vulnerable endpoint.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm User Frontend plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'User Frontend' or 'User Frontend - Post, Profile, Form, Login, Registration Plugin' in the list
    Affected if The plugin is present in the WordPress installation
  2. Identify the installed version
    Click 'View Details' on the User Frontend plugin entry in the plugins list to display the installed version number
    Affected if The version displayed is 4.2.8 or lower
  3. Verify the draft_post function is accessible
    Check if the wp-admin/admin-ajax.php endpoint responds to actions named draft_post or similar frontend submission actions by inspecting plugin source code in wp-content/plugins/wp-user-frontend/
    Affected if The draft_post() function exists and is hooked to an AJAX action without capability checks
  4. Review user role settings
    In WordPress admin, go to User Frontend > Settings and check if any public-facing forms are configured to allow draft post submissions without login
    Affected if Public forms are enabled that can submit to the vulnerable draft_post() function

A user is affected if the User Frontend plugin version is 4.2.8 or lower AND the draft_post() function is accessible to unauthenticated users, allowing them to modify arbitrary posts via the post_id parameter.
